Since ADF has been cited, I thought I'd back it up with a few quotes from the scripts:
Star Wars 4th draft:
They look for an exterior bridge control while the stormtroopers on the opposite side of the hatch begin making ominous drilling and pounding sounds.
LUKE
They're coming through!
LEIA
The controls must be on the other side.
Luke notices something on his stormtrooper utility belt. He pulls out a thin nylon cable, swings it across the metallic gorge and it wraps itself around an outcropping of pipes. He tugs on the rope to make sure it is secure, then grabs the princess in his arms swings across the treacherous abyss to the corresponding hatchway on the opposite side.
Just as Luke and Leia reach the far side go the canyon, the stormtroopers break through the hatch and begin to fire on the escaping duo. Luke returns the fire before ducking into the tiny sub hallway, closing the hatch behind him.

I'm afraid the controls are on the other side!
Luke notices something on his stormtrooper utility belt. He pulls out a thin nylon cable, swings it across the metallic gorge and it wraps itself around an outcropping of pipes. He tugs on the rope to make sure it is secure, then grabs the princess in his arms. Leia looks at Luke, then kisses him quickly on the lips. Luke is very surprised.
LEIA
Just for luck. We're going to need it.
Luke pushes off and they swing across the treacherous abyss to the corresponding hatchway on the opposite side. Just as Luke and Leia reach the far side go the canyon, the stormtroopers break through the hatch and begin to fire on the escaping duo. Luke returns the fire before ducking into the tiny sub hallway, closing the hatch behind him.
Evidence seems to be lacking from the pen of Lucas. No miss here.
