Felltower Prep & Explosives

Quoted from one of my players, reason number a gajillion why I don't let my players have explosives.

"See yous round 1100 hours -- we have a spaceship to explode."

Luckily for me they don't have the capability to explode the spaceship - and it would be a starship, anyway, wouldn't it?- so all my mini hunting, rules reading, and detail writing isn't going to go up in one earth-shattering KABOOM.
