Port Authority looks into blown-off AirTrain doors

HOWARD BEACH — The Port Authority has been investigating what caused the doors to be blown out of an AirTrain car that was in the shuttle’s maintenance yard early Friday morning.

The incident took place around 3:30 a.m. at the facility near the AirTrain’s Howard Beach station, a spokeswoman for the PA said.

Service was not interrupted during the morning rush and no passengers were on board the train when the doors came off, according to the spokeswoman.
