## Description of the bug
Facehuggers have the ability to leap into orbit around the planet.

## What's the difference with what should have happened?
Facehuggers should not have the ability to leap into orbit around the planet.

## How do we reproduce this bug?
1. Stand in front of dropship as it's launching
2. Leap at the pilot through the windshield, timing it to finish when the dropship is gone.
3. Achieve stable orbit.

Start with the listed reproduction steps: reproduce a facehugger leap at the dropship as it launches, then trace the behavior involved in that leap. The issue is done when facehuggers can no longer leap into orbit or otherwise remain airborne after the dropship departs.
