A second United flight departing Newark in as many days had to make an emergency landing Sunday morning.

The Federal Aviation Administration said United Flight 409 bound for Seattle returned to the Newark Liberty International Airport around 9:15 a.m. after reports of possible smoke in the cabin and cockpit, the Associated Press reported.

A United spokesman said the flight crew noticed an unusual smell in the cockpit. No injuries were reported.

On Saturday night, a United flight to Germany had to return to the airport after experiencing engine problems.

On Sunday, the FAA said one of the engines on the Berlin-bound flight apparently overheated on takeoff. An agency spokeswoman said that contrary to published reports, the aircraft didn’t blow a tire during takeoff
