Passengers had to use an emergency slide to evacuate a smoking American Airlines jet at Denver International Airport.

Passengers onboard a Turkish Airlines flight were evacuated after smoke was spotted in the landing gear. In video footage obtained by local Turkish outlet Mynet, passengers are seen panicking at the foot of deployed emergency exit slides. Both adults and children run away from the aircraft as rescue crews appear in the background.

Part of the plane’s landing gear caught on fire during its departure from Denver International Airport on Saturday, according to Denver7’s reporting. The Miami-bound American Airlines flight 3023 reported a “maintenance issue” with an airplane tire about 2:45 p.m. and aborted takeoff, airline and federal officials said.
