Houston, TX -
A Southwest Airlines Boeing 737 took off from Houston with its cargo door still open, it was heading to Dallas. The pilots of the airplane said they were not alerted to the open door in advance, acceding to a Southwest spokesperson, and reportedly no other aircraft or ground crew was paying attention enough to notice the large door.
The plane set off an alert right after take-off said Southwest, and the pilots returned to Houston to have the door checked.
