In his book 'My years with the IAF', former Air Chief Marshal PC Lal recollected how at around 1448 hours, the radar picked up the four Sabres as they pulled up in a north westerly direction to about 2,000 ft (610 m) above ground level. Within a minute, the ORP at Dum Dum was scrambled. Four Gnats took off by 1451 hours led by the formation leader Flt Lt Roy Andrew Massey. It was less than three minutes from the time the Sabres were detected by the radar.
