The Southwest Boeing 737 Max flight makes an emergency landing in Orlando a few minutes after takeoff.

Still struggling with the aftermath of two fatal crashes in the last six months and serious questions about the safety of his 737 Max aircraft, the situation got darker for Boeing on Tuesday when a Boeing 737 Max 8 from Southwest Airlines was forced to make an emergency landing in Orlando shortly after takeoff. The flight included a crew of two, but there were no passengers on board, as the Boeing line had not yet been allowed to fly again by the FAA. The plane was in the air so it could be moved to southern California where it had to be stored until the technical problems of the 737 Max were solved.

Southwest Flight 8701 took off from Orlando International Airport at 2:50 pm Tuesday, but was forced to return a few minutes later after the pilots reported an engine problem. "The crew followed the protocol and landed safely at the airport. The flight was supposed to go to Southern California Logistics Airport in Victorville, California, for short-term storage, "Southwest said in a statement. "The Boeing 737 MAX 8 will be transferred to our maintenance center in Orlando for review."

The engine problem is believed to be unrelated to the aircraft's automatic anti-stall system, which is currently under investigation following the crash of Lion Air Flight 610 shortly after taking off from Jakarta, Indonesia ) and Ethiopian Airlines Flight 302, which crashed a little over two weeks ago. At the time of the grounding, Southwest had 34 of the 70 Boeing 737 Maxs in service in the United States.
