-   -   Loud boom noise in Bangalore (https://www.team-bhp.com/forum/shifting-gears/222648-loud-boom-noise-bangalore-3.html)

For a "routine test flight" I seem to have heard it in Bangalore for the very first time! May be the global crash in the crude allowed our folks to use some jet propellant after all! Poor us!

Mysterious loud sound heard in Bangalore.

So, Bangalore gets a Bang.
While Dhanbad waits for Dhan,
Chandigarh for Chandi,
Amritsar for Amrit,
And Lucknow for some Luck.
(Yes, you can do the rest, but avoid London)

Never have I experienced such a boom and reverberations. This is definitely something new. They say, lack of noise and changes in the environment (post lockdown) made it more apparent but I dont buy it

I am again hearing the aircrafts in air. So there might be more such bangs in Bangalore today too !

Although IAF says they fly outside city, they are always flying over the city. Its funny that myself and everyone across city thought it was a transformer :) Reflects so much on BESCOM.

No. It's illegal to fly supersonic over indian airspace. However I'm not sure if the armed forces are subject to this regulation.

Dont know about southern part of India, and their experiences with sonic boom. Here in north, sonic booms were part of our growing up years routine. 2-3 booms a month, maybe more, we are quite used to ghddddghd
Ghddddd trnnn trnnn shoooonnn.
Sirsa, ambala, chandigarh, halwara, & more all within 100-200km radius, we even used to hear ear shattering dog fights during terrain hugging exercises too, where you could actually see the pilot in the fighter if you are out at the opportune time.

I stay very near to HAL but it's first time such boom sound was felt. But don't think it happened first time in Bangalore considering IAF/HAL heavy presence here, possibly current lockdown may have made it more pronounced to rest of the city.



I agree. During my childhood, I've frequently seen fighter jet squads of 3-4 planes flying low at supersonic speeds (when you hear the jet sound after it has passed), and have once seen a Mig-29 pliot from my college's terrace when it made a very slow & low pass. It's more evident to people living close to IAF bases along India-Pak border, we used to stay within few kms of IB.

Am I the only soul in Bangalore who hasn't heard this yesterday. During that time I was driving from Hosur Road Prerana Service station towards Marthahalli. I didn't hear any sound! When I reached home everyone at home had heard this and were only talking about this!!

Just mins before the sound, fighter jets were doing sorties (heard the flight sound also clearly).
I was driving down to my home via Hosur road and I heard the sound. It was loud.
May be you were busy into something that you did not pay attention to.

You must have been "busy driving!"...were you by any chance driving an E-Class - has the quietest of cabins?

Is the IAF upto something? So many tests, training and flights near the unusual civilian areas. We never had fighters here in Ranchi except for a few air shows but this is what I wrote last week In another thread:

There was nothing in the local media about this either.

In Pune we regularly hear the booms from the airforce fighters in the morning hours (the same time when Pune airport is closed for operations).
Nothing new.

Just speculating here but perhaps since there haven't been regular commercial flights during the lockdown, the military test flights or sorties are able to fly a different pattern over Bangalore or lower because of clear skies without usual air traffic? So maybe that explains the unusual boom?

I live very close to the old airport/HAL divisions too and while loud engine noises and chopper noise is regular, first time I've heard something like this. Heard it even though I had headphones on and was listening to music and working. House windows shook definitely. But then again, because of the way houses are stacked up right next to each other in my area, some windows shake even when my neighbors bang their car door!

Like most of Bangalore, I too thought it was a blown transformer, cheers BESCOM! :)

I dont know if everyone is referring to the same sonic boom. Our office (and most of people's on this forum) is near the HAL airport. We hear real loud noise of little higher frequencies lot of time.

I worked in Golf View campus on Wind Tunnel road, at the edge of the airport runway and had building windows vibrate etc. They were 50 metres away landing and taking off.

But this was an explosion. I hope this is how a sonic boom is and its very different from the very high sound you hear from military aircraft normally.

My office campus is right next to the HAL airport runway and most of the time our conversations are muted by aircrafts taking off and landing. However, we absolutely did not feel or hear this so called Boom sound. I got to know about this from my wife about an hour later. At times i think such instances get blown out of proportion.
