On the ground, a sonic boom sounds a bit like thunder or an explosion. Simply put, they are shockwaves produced by planes or other objects that are flying at a speed equal to or greater than the speed of sound.
“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,” the MoD added on Twitter. The test flight was carried out by the IAF’s Aircraft and Systems Testing Establishment which is based in Karnataka’s capital city. Putting all speculation to rest, the Ministry of Defence (MoD) said it was a “routine IAF Test Flight involving a supersonic profile which took off from Bengaluru Airport and flew in the allotted airspace well outside City limits”. Residents of Bengaluru, who are still trying to figure what lockdown 4.0 means for them, were distracted on Wednesday afternoon by an unusual sound that rattled windowpanes and triggered memes and conspiracy theories, with the more fanciful ones even bringing aliens into the picture.Ĭonfirmation that it was, in fact, a sonic boom caused by an Indian Air Force (IAF) jet came late in the evening.
