Boeing found debris in the gas tanks of some of several hundred undelivered 737 Max jets, a potential safety hazard and yet another problem for the company as it tries to get the planes airborne again after two deadly crashes.

Mark Jenks, a Boeing vice president and general manager of the 737 program, sent an email addressing the problem — known as foreign-object debris, or FOD — to all employees in the 737 program.
