Around 10.30 am on Thursday morning, residents of Tiruppur town, Dharapuram and Palladam areas in Tiruppur district were alarmed by a sudden loud sound heard from the sky, that led to panic among some. As people started speculating about what the sound could be, Tiruppur Collector Vijayakarthikeyan tweeted that the loud noise was most likely caused by a supersonic aircraft. He further asked people to not spread rumours.
Twenty-nine-year-old Naratajan who works as a marketing personnel at a dying factory in Tiruppur tells TNM that when the sound was first heard, he thought perhaps the boiler in his factory had burst. â€śThat was how it sounded. We immediately ran to check and found the boiler to be functioning perfectly. We then thought that may be somewhere in the vicinity, a factory had a boiler blast,â€ť he says over the phone.
â€śI have not felt it before but first there was a mild tremor, then the loud noise. You may not understand if I explain. It was a very mild sensation, like the ground beneath you shaking,â€ť Natarajan says.
Soon, Natarajan noticed those near him receiving phone calls. â€śMy friendâ€™s wife called him saying she felt a vibration and asked him if it might be an earthquake. Theirs is a compound with 15-20 houses. Apparently all of them had come out as soon as they heard the sound,â€ť he adds.

However, it was not long before the residents of Tiruppur put two and two together, and related it to a similar incident that took place in Bengaluru a few days ago. â€śThen people began understanding that it was something similar to what happened in Bengaluru last week. Our Collector too clarified,â€ť Natarajan says.
On May 20, around 1.30 pm, Bengaluru residents experienced the mysterious thunderous noise. Later that evening, Ministry of Defence, Bengaluru clarified in a tweet that the loud sound was caused when a routine Indian Air Force test flight, with a supersonic profile, took off.
