The wreckage of a Continental Airlines plane that crashed at Denver International Airport is in the process of being moved to another spot at the airport.

The plane has been resting on its belly at the bottom of a ravine since Dec. 20, when it veered off a runway during takeoff. Workers loaded the fuselage onto three flatbed trucks Friday, but soggy ground has so far prevented them from taking the pieces to a nearby hangar.

All passengers and crew members escaped the fiery crash. Thirty-seven people were injured, including the pilot, but all have been released from hospitals.

Investigators are still trying to determine what caused Flight 1404 to Houston to crash.
