Corrected entry: When Luke and Darth Vader are fighting and Darth Vader is hurling things at Luke, one thing he throws flies through the window and makes a giant hole. However, when Luke gets sucked out, the hole is twice as big even though nothing else went through it.

Correction: There is clearly a vacuum (or at least drastically reduced air pressure) on the other side of the window. The suction created by the pressure differential could have easily sucked more of the broken window out.
