A Southwest Airlines flight aborted takeoff at Chicago's Midway International Airport late Wednesday night due to a mechanical issue, the airline said.
All of the flight's 143 passengers were safely evacuated and returned to the terminal, and no injuries were reported. A spokesperson for the Chicago Fire Department said Thursday that one of the Boston-bound plane's engines caught fire.
One passenger recorded footage of an apparent explosion on the Boeing 737's starboard-side engine:

A Southwest spokesperson said the airline is still awaiting reports on the incident. The company did not immediately respond to Mashable's request for comment.
