She pulls hard

There was no time to lose. Dana used her last reserves of strength to pull her body inside. She felt the rough metal frame of the window graze against her hips and butt, shortly followed by a "rrrrip" sound.

The wind was knocked out of her sails as her lower body landed on the ground with a small thump. She heard someone exclaim "Who's there?", and heard footsteps approaching her.

Alarm bells rang in her head. She didn't have time to move, as that would cause more noise. She patted her butt, and found a small horizontal tear near the apex. Thinking quickly, she covered the rip with her hand, as she closed her legs in order to hide the other damage to her suit.

The door opened, and a guard with a flashlight appeared. He surveyed the room, trying to find the source of the noise.

Dana held her breath.
