Delta flight drops to 9,000 feet after pressurisation failure
A Delta airplane had trouble keeping the air pressure inside the cabin normal.
This happened shortly before the plane was supposed to land in Salt Lake City.
The airplane quickly flew down to about 9,000 feet.
Oxygen masks dropped so passengers could use them during the descent.
Some passengers reported ear pain and said the experience was frightening.
The pilots then diverted the plane to Las Vegas.
The plane landed safely there and later continued to Salt Lake City.
Reports suggested a small valve or software problem may have caused the issue.
A Delta Air Lines Boeing 737-900ER rapidly descended near Salt Lake City.
Oxygen masks deployed after a suspected cabin pressurisation system failure.
Pilots descended to roughly 9,000–10,000 feet so passengers could breathe normally.
The aircraft diverted to Las Vegas and landed without reported problems.
After a possible valve or software issue was addressed, it continued to Salt Lake City.
