The Jet Airways plane turns around after its passengers suffered nosebleeds, ear bleeds

"The B737 aircraft, with 166 guests and 5 crew members, has landed normally in Mumbai," said Jet Airways. said in a statement. "All the guests were safely landed and taken to the terminal, and first aid was given to a few guests who complained of ear pain, nosebleeds, etc."

A Civil Aviation Directorate (DGCA) official told CNN affiliate CNN News 18 that the crew would have forgotten to press a button to put the cabin under pressure.

In the declarationJet Airways said that flight 9W697 "had the air back because of pressure loss in the cabin". A spokeswoman declined to confirm the statement that the crew had forgotten to press the button.

Videos of the flight posted online showed passengers wearing oxygen masks, which automatically deploy in case of pressure drop.

"I've seen a lot of people bleed from the nose," passenger Joel D'Souza told CNN. "I took off my oxygen mask for a second and I felt so stuffy and hot in the cabin." There was no announcement from the team and nobody knew what to do. "

He stated that he and other passengers had since flown another flight about 11:00 am local time.

Jet Airways said the crew of the flight cockpit "was put out of service while awaiting the investigation" and that alternative arrangements were in place for the passengers on board.

For this reason, planes are pressurized to simulate a lower altitude inside the cabin. As the aircraft climbs to high altitude, the cabin is pressurized and as it descends to land, it is gradually depressurized.

Low pressure air is thinner and drier, which can cause nosebleeds.
