The Kolkata-bound flight was flying at 36,000 ft in the Bangladesh airspace while the Guwahati-bound flight was safely flying at 35,000 ft. This was when the Bangladesh ATC asked the former to descend to 35,000 ft, breaking the 1000 ft rule.
Air India, impressed by its captain’s feat, lauded Anupama Kohli. The woman pilot - with an experience spanning 20 years, showed grit and determination, to avert the major mid-air tragedy.
