No aliens, no Avengers: Def Min says Bengaluru boom from routine IAF test flight

Aviation
The Ministry of Defence added that the aircraft which caused the sound was far away from Bengaluru city limits.
The mystery of the loud boom that had people concerned, amused and guessing in Bengaluru on Wednesday has finally been solved with a late night admission from the Indian Air Force. The Ministry of Defence, Bengaluru said in a tweet that the loud sound that was heard in several parts of the city on Wednesday afternoon was caused by a “routine Indian Air Force test flight”, with a supersonic profile, taking off.   “It was a routine IAF Test Flight involving a supersonic profile which took off from Bluru Airport and flew in the allotted airspace well outside City limits. The aircraft was of Aircraft Systems and Testing Establishment (ASTE) whose Test Pilots & Flight Test Engineers routinely test out all aeroplanes. The sonic boom was probably heard while the aircraft was decelerating from supersonic to subsonic speed between 36,000 and 40,000 feet altitude,” the statement said. The statement claimed that the aircraft which caused the sound was far away from Bengaluru city limits. “The sound of a sonic boom can be heard and felt by an observer even when the aircraft is flying as far away as 65 to 80 kilometres away from the person,” it said. The thunderous ‘boom’ sound was heard by several residents in many parts of Bengaluru around 1.30 pm. The IAF Training Command had, in an earlier statement, denied that it was caused by a training sortie. However, the Training Command had confirmed that the aircraft could be flying under the IAF’s testing wing, ASTE, or by the Hindustan Aeronautics Limited (HAL). Sources at HAL had earlier hinted to TNM that a Sukhoi Su-30 aircraft of ASTE’s took flight from HAL at the time the boom was heard. ASTE uses HAL's grounds near Old Airport Road to test its aircrafts routinely. The Sukhoi Su-30MKI is an aircraft developed by Russia and is built under HAL’s license. It has the highest speed of 2,120 kmph, and can carry radars, missiles, bombs and rockets.

Officials have finally said that a Sukhoi-30MKI jet flew across Bengaluru skies but have not concluded that it was the source of the loud ‘boom’ that was heard over the city on Wednesday afternoon. Residents from multiple areas of the city described a “thunderous” noise” and many felt tremors as well. The Air Force-Training Command on Wednesday evening denied that its sortie was involved, but confirmed that the flight may have been flown by the Indian Air Force’s (IAF) testing wing, known as the Aircraft & Systems Testing Establishment (ASTE) or by Hindustan Aeronautics Limited (HAL).  "No aircraft of Training Command was flying in the area. However, ASTE and HAL could have been undertaking their routine test flying, which necessitates going supersonic at times. These are done well beyond the city limits in specified sectors,” according to the statement. “However, considering the atmospheric conditions and reduced noise levels in the city during these times, the aircraft sound may become clearly audible even if it happened way out from the city," according to the statement. TNM asked three former Indian Air Force officers whether a 'sonic boom' by a fighter jet would be allowed to occur within a city's airspace. The officers all explained that though fighter jets are allowed to fly in Bengaluru's airspace, it is rare that residents would feel the impact of a sonic boom. Former Air Chief Air Marshal S Krishnaswamy said, “There are certain altitudes of above 10 kilometres from the surface [of the ground] and there are certain corridors on which we can fly at supersonic speeds. These corridors are away from the cities.” “However, it is possible that due to certain weather conditions and wind conditions that the altitude has to be lowered. But normally for testing purposes, they are very well planned," he added.  He further stated that there have been other occasions in the past when window panes have shattered due to jets flying overhead.  Similarly, former Vice Chief of Air Staff, Air Marshal PK Barbora said that it is rare for armed forces to fly at supersonic speeds close to cities like Bengaluru. “There are restrictions, as long as I was in the service and it is probably still there. We cannot go over populated areas. The sound waves can actually crack buildings. Unless there is an occasion in which the government authorises a sonic run, like a fire power or Navy Day demonstration, we then do it at a height and distance from the public so that there is no impact on human beings or structure,” he told TNM. He added, “We are only allowed to do it within our own areas where no other aircraft are flying and we will do it at a height, as per our mission directive for training. So around 20,000 feet, there will be only impact on the sound you might hear. What happens when you cross the speed of sound, pressure waves are formed and it hits your eardrums. It sounds like a boom. Now depending on how close you are, the pressure wave can cause damage to human beings as far as eardrums are concerned.” Former Air Force spokesperson and an ex-Group Captain Tarun Kumar Singha said pilots generally avoid flying close to the ground or near populated areas, except during the Aero India event or other such air shows in Bengaluru, to ensure there are no obstacles while flying. “Otherwise it is always done at high altitude, even for testing purposes, where the sound which you hear from the ground is weaker than the sound of lightning,” he said. However, he said broken glass panes may not necessarily be due to the sonic boom. The mysterious noise was heard in the city’s Whitefield division, and as far as Cooke Town, Vivek Nagar, Ramamurthy Nagar, Hosur Road, HAL, Old Madras Road, Ulsoor, Kundanahalli, Kammanahalli, CV Raman Nagar, and HSR Layout.

‘Don’t dilute labour laws’: Trade unions in Karnataka protest proposed changes

Labour
The latest demands have received support from representatives of ASHA workers in the state who seek to be covered by labour laws.

In light of the economic downturn due to the nationwide COVID-19 lockdown, many states, including Uttar Pradesh, Bihar, Rajasthan and Odisha, have made key changes to labour laws. From the suspension of nearly all labour laws, including the Minimum Wage Act, in UP to the new 12-hour workday in states like Gujarat and Punjab, the sweeping changes in over a dozen states in India have alarmed trade unions. Closer home, in Karnataka, the state’s announcement that it was mulling its own ‘brand of reforms’ to labour laws met with backlash from activists. In a meeting with industry representatives, the Labour Department had said that it was considering increasing overtime paid working hours from 72 to 100 hours per annum. The sudden shunting of Labour Karnataka IAS officer Manivannan P from his role and his replacement with M Maheshwar Rao IAS, Principal Secretary of the Commerce and Industries Department, had led to allegations of conflict of interest.  On Tuesday, various trade unions in Karnataka held a protest before the Labour Department in Bengaluru, demanding that the government stop attempts to dilute labour laws in the state.  National trade unions have announced a nationwide bandh on Friday, May 22. “In the past few weeks, governments and industry bodies have been speaking of the need to relax labour laws. The government has also announced huge relief packages for industries. Seen together, all this seems like the government just considers workers to be machines who create profit. The government does not seem to see that workers are people with needs, that they are an important part of our democracy who need to play their roles as active citizens,” a press release from the All India Central Council of Trade Unions (AICCTU) said. Anticipating a similar move in Karnataka following the local industry bodies meeting with government representatives, trade unions in Karnataka have written to the Chief Minister to not reduce the rights of workers and instead, offer better solutions. “What is evident is that the previous system did not work. People who were earning everyday were left with nothing and had no social security and no savings. Why is it so? Because people were not earning enough and yet, profits of companies kept growing. There is a high disparity. We need to acknowledge that this is the root of the problem. While middle class people are satisfied with what they have, it is the poor who suffer,” said Maitreyi Krishnan of the AICCTU. ‘Reduce working hours’ Instead of upping the workday to 12 hours, the government should look into reducing it to six hours in the Factories Act, 1948, the release said. “This is not a new concept and has been adopted widely in European countries. Reducing work hours would allow factories to hire more people, and thus, deal with the widespread problem of unemployment. When people are forced to work for the job of two people for the same or less pay, then productivity suffers,” Maitreyi said. She added that making people work constantly was depriving them of active citizenry. “Besides this, the workers would be able to use the extra time to educate themselves in order to become better citizens, spending that time in engaging with the political and social sphere, and picking up skills for upward mobility. Such a move would uplift the entire society, and make it more equitable,” Maitreyi said, adding that workers should have a say in the company’s management. ‘Include ASHA workers’ The latest demands have also received support from representatives of ASHA (Accredited Social Health Activist) workers in the state who seek to be covered by labour laws.  D Nagalakshmi, Secretary of the Karnataka State ASHA Workers Association (KSAWA) said, “The government should first look after those providing essential services. The government should amend the labour laws to include the over 3.5 lakh women who work for the government as ASHA health ‘activists’, and anganwadi cooks in government schools who provide hot meals to children. These women should be considered workers, and not activists, and brought under the ambit of (existing) labour laws.” ASHA workers have been key workers during the ongoing COVID-19 pandemic, helping authorities contact-trace potential infections. However, activists said, the workers have not received their due. Nagalakshmi pointed out that often, women are not formally acknowledged as workers. “This is evident in the non-recognition of domestic workers as well. Construction workers, primarily men, can get registered as labourers and get an identity card. They are able to avail benefits using this card, including health and education benefits. But no such facility is available for domestic workers who are primarily women,” she said, calling on the government to set-up a domestic workers’ welfare board. MNREGA for urban areas The AICCTU has proposed that a scheme like the National Rural Employment Guarantee Act (MGNREGA) be adopted in urban areas too. “This will ensure that the urban poor are not as affected by unemployment as they were during this lockdown emergency,” Maitreyi said. Another key demand from trade unions is that contract workers be paid the same wages as those with permanent jobs, as per ‘equal pay for equal work’. The press release quoted BR Ambedkar’s address to the 7th Indian Labour Conference held in November 1942.  “How can the workers be asked to agree to reduce standards of living in an economy in which the profits are to go to private individuals? We must do our best and do it immediately to mitigate it and to prevent it from lowering labour standards. I believe three things are necessary to ease the situation. Firstly, to reduce hours of employment so as to provide employment for many. Secondly, to provide machinery for fixing wages. The absence of such machinery combined with employment is bound to cause labour standards to slump, which ought to be prevented. Thirdly, to provide the employers and workers with a resolve to collective bargaining and learn to work together in the solution of other common problems.” BR Ambedkar had said.

Karnataka reported 67 new cases of COVID-19 on Wednesday, bringing the total number of cases in the state to 1,462. Of these, 884 persons are currently under treatment. Among the 67 people who have tested positive on Wednesday, 52 have travel history. The majority of them – 51 people – are those who came to Karnataka from Maharashtra. Meanwhile, one person with travel history from Visakhapatnam also tested positive for COVID-19. Four new cases were reported in Bengaluru. The details of the Bengaluru cases are as follows: patients 1396 and 1397 were ‘urban contacts’ from Bengaluru, whose contacts are still being traced. The other two patients were reported to be secondary contacts of patient 701, who is a 49-year-old woman from Bengaluru, who reported with influenza-like illness (ILI). The other new cases were reported from Hassan district (21), Bidar district (10), Mandya (8), Kalaburagi (7), and Udupi (6). Tumakuru and Raichur reported four cases each, while Uttara Kannada, Dakshina Kannada, Yadgiri have reported one case each. One person has reportedly succumbed to the disease on Wednesday, bringing the total number of COVID-19 deaths in Karnataka to 41, including one person who had the coronavirus but died due to non-COVID-19 cause. The most recent death is that of patient 1256, who was admitted in a private hospital on March 18, after testing positive for the virus after a trip to Tamil Nadu and back. He passed away in the private hospital on Wednesday. 13 people have been discharged as of May 20 evening. So far, 556 people have reported as recovered from COVID-19 in Karnataka and have been discharged. “We are having no problems with transmission of cases from inter-district movement. The problem is that cases are being imported from other states with high numbers of COVID-19 cases, which is why the Chief Minister has categorically banned travel and entry from these states,” Education minister S Suresh Kumar had said, during a press conference on Wednesday.

Was a Sukhoi-30 behind ‘boom’ sound in Bengaluru? IAF yet to confirm

Bengaluru
ASTE, the testing wing of IAF, uses HAL's grounds near Old Airport Road, to test its aircraft regularly.
Bengaluru Metro Pillars picture from MG road
Residents in several parts of Bengaluru heard a loud ‘boom’ sound around 1.30 pm on Wednesday. While some described it as a ‘thunderous noise’, others said they felt tremors, with their window panes rattling for as long as five seconds. The sound was heard as far as Cooke Town, Vivek Nagar, Ramamurthy Nagar, Hosur Road, HAL, Old Madras Road, Ulsoor, Kundanahalli, Kammanahalli, CV Raman Nagar, Whitefield and HSR Layout in the city. Several social media users stated that they could feel vibrations for about five minutes. A top police official told TNM that it could be a Sukhoi-30 jet flying over Bengaluru skies. The Air Force has not confirmed yet and told TNM at 4.10 pm that they were still 'ascertaining what caused the sound'. Some pointed out that Hindustan Aeronautics Limited (HAL) could be conducting regular flight tests of light combat aircraft (LCA). "It has nothing to do with HAL aircraft," an HAL spokesperson told TNM, when asked about the incident. However, HAL sources hinted that a Sukhoi 30 belonging to the IAF or IAF Aircraft & Systems Testing Establishment (ASTE) took off from HAL around the same time the booming sound was heard. The source said, "We have not issued anything official because the huge bursting sound cannot be attributed to this fighter with certainty though it took off around this time. It is too early to say whether it was due to the aircraft as it will be mere speculation." ASTE, the testing wing of IAF, uses HAL's grounds near Old Airport Road, to test its aircraft regularly. Sukhoi-30MKI is a twin-jet, twin-seat aircraft developed by Russia and built under license by the Hindustan Aeronautics Limited. The Su-30MKI has a top speed of Mach 2 or 2,120 kmph. It has a maximum take off weight of 38,800 kg and can carry radars, missiles, bombs and even rockets. Bengaluru Police Commissioner Bhaskar Rao had earlier told TNM that no damage was reported anywhere in the city and no calls have been made to 100. “We have asked the Air Force Control Room to check if this was a flight,” he said, adding that they are waiting for the Air Force to confirm.

Heard a loud 'boom' in Bengaluru? Officials are investigating what it was

Blast
The sound was heard as far as Cooke Town, Vivek Nagar, Ramamurthy Nagar, Hosur Road, HAL, Old Madras Road, Ulsoor, Kundanahalli, Kammanahalli, CV Raman Nagar, Whitefield and HSR Layout in the city.
Representative
A loud blast was heard in Bengaluru on Wednesday afternoon at around 1.30 pm near the city’s Whitefield area. Many Bengaluru residents across several areas in the city took to social media to state that a loud ‘boom’ had been heard in the area. While some residents said they heard a ‘boom,’ and a ‘thunderous noise,’ others felt their homes shake and windows rattling for as long as five seconds.  Bengaluru Police Commissioner Bhaskar Rao told TNM that no damage was reported anywhere in the city and no calls have been made to 100. “We have asked the Air Force Control Room to check if this was a flight,” he said, adding that they are waiting for the Air Force to confirm. The sound was heard as far as Cooke Town, Vivek Nagar, Ramamurthy Nagar, Hosur Road, HAL, Old Madras Road, Ulsoor, Kundanahalli, Kammanahalli, CV Raman Nagar, Whitefield and HSR Layout in the city. Several social media users stated that they could feel vibrations for about five minutes A jet aircraft could be heard flying over Bengaluru. There is speculation that the sound could be a ‘sonic boom’ from a fighter jet flying over the city. A sonic boom is the result of fast movement of aircraft – the thunderous sound is produced when these objects fly overhead faster than the speed of sound.    TNM reached out to the Karnataka State Natural Disaster Management Centre (KSNDMC), who confirmed that it wasn’t an earthquake. "Earthquake activity will not be restricted to one area and will be widespread. We have checked our sensors and there is no earthquake activity recorded today," Srinivas Reddy, Director of KSNDMC. In 2005, too, a similar ‘sonic boom’ was heard in Bangalore. Some pointed out that Hindustan Aeronautics Limited (HAL) could be conducting regular flight tests of light combat aircraft (LCA).
