In a former job in the special effects business we built just about every
kind of launcher you can imagine: slingshots with 10 ft spread 20ft off the
ground and a 50 ft draw; air cannons to throw refrigerators hundreds of
feet; trebuchets, catapults, electric motor driven, etc. The pneumatic
launcher is by far the most repeatable, compact, aimable, etc. especially
if you want to drag a tether. The power source is consistent: unlike latex
tubing, which ages and is ozone and UV sensitive and temperature dependent,
or bungee cords; and unlike spring loaded mechanisms (can't store enough
energy).
It also has the least chance of being perceived as a weapon. For example,
big slingshots are marketed as weapons, so the onus is on you to explain
why it isn't a weapon. A pneumatic launcher can be made very innocuous in
appearance.
