A United Express flight Wednesday abruptly declared an emergency and landed at Buffalo Niagara International Airport.It was initially thought there was a problem with the cabin pressure system but SkyWest spokeswoman Marissa Snow says it was three passengers who passed out and were later treated and released.
SkyWest flies as United Express. Passengers, apparently were not informed of what was happening during the abrupt landing.
"The scariest thing really was the nose dive that happened," said passenger Vanessa Bergmann.
"It was very obvious that we were descending as rapidly as we could at that point."
SkyWest says the plane dropped 26,000 feet to bring the plane into breathable air in case there was a pressurization problem. The flight was from Chicago-O'Hare to Hartford and the other 74 passengers made it to the Connecticut city hours later.
