Authorities swarmed a commercial jet that landed at LaGuardia Airport from Florida Tuesday after the Delta flight crew noticed a "smoky odor" coming from the cockpit, the airline said in a statement.
The crew of flight 2522 shut down both engines out of an abundance of caution and the Port Authority police's ARFF (Aircraft Rescue Firefighters) unit responded, a Delta spokesman said.
The plane, an MD-88 aircraft that seats up to about 170 people, was towed to the gate, where customers deplaned normally, the airline said. It wasn't immediately clear how many people were on the plane, but passengers tweeted photos of investigators in suits combing the aircraft with high-tech gear.
Maintenance is evaluating the aircraft. No injuries were reported.
"The safety of Delta's customers and crew are always our top priority," the airline said in a statement.
