Here's a comment on that video from someone who seems to know what he's talking about
:
-Unknown to anyone, a wire in a junction box was accidentally pinched under the cover causing a short to ground.
-After takeoff, the landing gear was selected up but the hydraulics shut off because the shorted wire.
-When the hydraulic pump shut down the pressure was lost
and air loads on the unlocked gear caused it to drift rearwards into the door.
-the nose wheel tire was cut by the gear door.
-engineers on the ground gave instructions to the pilots where and how to jump a relay in the cockpit
to get the hydraulic pump started.
-Copilot use a paperclip and jumped terminals on a relay as instructed.
-Hydraulic pump started and pilot selected gear down, and the gear went back to down and locked.
-Aircraft landed normally but the anti skid system malfunctioned and locked some of the wheels
