American Airlines flight 4837 from Indianapolis to Chicago rejected takeoff on Saturday morning when smoke was reported in the cabin. The Republic Airways Embraer ERJ175 was accelerating on runway 5L at the time.
Some of the 67 passengers on board were “crying and kind of screaming and you could see people praying,” according to one man on the flight, after they “started seeing smoke coming from the cabin door and smelled something burning.”
