Overheard at a LAN party while playing the Wake Island map for Battlefield 1942: "What's the key to open your parachute? …oh, never mind."

This sort of skill provides good examples of when not to use the system. If the scenario is about doing an infiltration, well, you can open with the team packing up and burying their chutes; you don't have to say "everyone roll, oh dear Bob crit-failed, he can go and get the pizza". If you're not prepared for something interesting to happen on that crit-fail, you shouldn't allow it to happen at all.

On the other hand, scattered characters and landing injuries are entirely in-genre and to be encouraged, especially if the PCs have a wide range of skill levels.

Ultra-Tech doesn't talk about high-tech parachutes, though I think one can probably assume they continue to get lighter, and less prone to fail to deploy. Its alternatives are actual flying vehicles, like the contragravity belt and nuclear jetpack, for which see Piloting.
