SkyWest Airlines says a flight from Iowa to Detroit made an emergency landing in Milwaukee after a sudden loss of cabin pressure.
SkyWest spokeswoman Marissa Snow told the Journal Sentinel that the plane carrying 38 passengers and three crew members left Cedar Rapids at about 7 a.m. and landed safely in Milwaukee at about 8 a.m. Thursday.
Snow says one passenger was treated at a hospital because of a painful ear.
She says the passengers continued on to Detroit on different plane while mechanical crews investigated what caused the loss in cabin pressure.
The Federal Aviation Administration is also investigating.
SkyWest is based in St. George, Utah.
