The FAA is investigating after an American Airlines flight taking off from Denver International Airport was evacuated following an incident with the plane's landing gear during its takeoff. Flames could be seen around the landing gear of the Boeing 737 Max on Saturday afternoon.

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.
