Incredibly, cabin crew failed to pressurise the cabin of the B737 aircraft, which landed safely with 166 plus five crew on board.
Larit Gupta, a senior official with the department, told the Hindustan Times newspaper that the crew had forgotten to activate a switch to maintain cabin pressure. "As per initial information, out of 166 people on board, 30 passengers have nose bleeding, few have ear bleeding and some are complaining of headaches". "Some of us experienced nose bleeding and headache", Darshak Hathi, a passenger said. The pilots have been taken off duty, pending investigation, a Jet Airways spokesperson said.
The Aircraft Accident Investigation Bureau has started an investigation.
"Jet Airways regrets the inconvenience caused to its guests", it said in a Twitter post. Another passenger, Satish Nair, claimed after the cabin pressure dropped, there were "no staff" to help and no instructions given when the oxygen masks deployed.
Pilots operating a Jet Airways India flight on Thursday forgot to turn on a switch that maintains optimal pressure in the cabin during ascent, causing injuries to some passengers.
As a result, the plane was forced to return to Mumbai.
