A United Airlines jet cut short a flight Wednesday and landed in Tampa, Florida, after pilots were alerted about a possible issue with a door, according to an airport spokesperson. Last week, a plug that takes the place of a door on some Boeing Max 9 jetliners blew off an Alaska Airlines plane shortly after takeoff from Portland, Oregon. An spokesperson for the Tampa airport said the initial report to emergency dispatchers was that the plane diverted because a door indicator light turned on.
