Actually, you probably would if physics were followed. I've seen the results of a Stryker driving out on an unfinished overpass. Fall was about 20 feet/6 meters (Short range by this game's standards), and it destroyed the vehicle and killed or injured most of the crew.
Prodigious size alone makes it hard to lift , Sil 4 objects are 4 difficulty anything larger than sil 5 is actually impossible and needs the spending of a destiny point to attempt.
Lifting a Sil4 object is easy: you need 65XP, 2 pips, and no difficulty check.
I should have said throw. However your probably not going to kill a vehicle by dropping it.
Physics and Star Wars do not like each other just Ask Neil Degrasse Tyson about ANH and he will tell you the only thing they got right is that in order for life to exist on Tatooine it would require that it's binary star system have its stars close together which it does.
Now that doesn't mean you can't apply physics to your game, I just won't cause I feel Star Wars throws it out the window anyway so it's not in my GM's toolbox for this specific game, other more realistic RPG's sure but this isn't really the place to say Physics is the be all end all.
There still needs to be some semblance of sensibility. If the game rules make falls horrifically dangerous for characters (presumably through 'physics' as an in-character explanation), why wouldn't such falls also have proportional effects upon vehicles?
