Test flight of iAF fighter triggers sonic boom

A test flight of an Indian Air Force (IAF) fighter jet had triggered a sonic boom over the city on Wednesday afternoon, sending its residents and officials into a tizzy, an official said. “It was a routine IAF test flight involving a supersonic profile, which took off from Bengaluru airport and flew in the allotted airspace outside the city limits,” said a defence official in a tweet much later. The mysterious sonic boom at around 1. 30pm rattled the citizens as well as the authorities in this aerospace hub, sparking rumours of an earthquake, an explosion or a fighter jet cruising at top speed. —
