cargo door

The boy and girl walk up to the helicopter, open the cargo door, take out their bags.

"And you are sure the cargo doors did not open in flight?"

The cargo door closed and air returned slowly into the bay.

It had windows on the side, and in the cargo doors.

Another forty-five minutes and we pulled up in front of the big cargo door.

After about four minutes, the cargo doors could no longer be seen over the edges of the bay.

A line ran straight up from the Shuttle's open cargo doors.

Then the cargo door opened, dazzling them with the sun.
