I discovered another glitch that occurs when you swap weapons while thrusting with the jetpack. It only works while thrusting in a direction but it allows you to reach a higher altitude and retrieve the furotech cell in Bay City that's worth 5. I used this in combination with the momentum storage glitch to access the rock early. If done properly it can possibly save time in Bay City-5 (The Guns of Alcatraz) during Any%.
