During the climb, the crew allegedly forgot to select the bleed switch, due to which cabin pressure could not be maintained, a senior DGCA official said.
As many as 30 passengers suffered bleeding and headache due to low air pressure inside the cabin of a Jaipur-bound Jet Airways flight on Thursday.
According to PTI, another unnamed passenger said that the plane "circled overhead for around half-an-hour before landing". Meanwhile, civil aviation minister Suresh Prabhu has ordered the DGCA to conduct a comprehensive safety audit of all scheduled airlines, aerodromes, flying training schools and MROs immediately.
Five passengers were shifted to Mumbai's Nanavati Hospital for treatment. "I saw a passenger sitting next to me bleeding from the nose".
