Q&A

Q: Why use 37mm launcher and not compressed air?
A: Significant portion of intended audience already has 37mm and 40mm launchers. They are easy to use and there's no learning curve.
The intended audience is already carrying 60+lbs of gear and making them carry a whole other system might make it not feasible.
Legal status - the 37mm is already designated as a life safety device by ATF, many of the potato guns etc are actually technically illegal under federal law and in many jurisdictions.
The air tanks would produce a slew of challenges to recharge during disasters. The shells are self-contained.

Q: The air tanks are heavy and can become a hazard under certain conditions. Ruptured pressure hoses can whip around injuring the operator. Cracks near the stem can turn the tank into a dangerous projectile.
A: Why not use camera x or y that costs $8 and uses SD card?
First of all SD card cameras are unusable as they would require the recovery of the camera to review - which defeats the whole purpose of using a launchable camera system.

Q: Why not use a cheap helicopter? A: Helicopters take a bit of time to learn to control and fly properly. Helicopters are actually the hardest type of aicraft to fly.
Consumer grade helicopters, even when expertly flown are very noticable and easilly detered or dissabled.
We conducted a few tests

Test 1
One test involved an electric RC helicopter attempting to sneak up on me from 200 yds away. I was entrenched and behind a barricade. The helicopter could be easilly heard from 30+ft away. The helicopter was easilly shot down in 3 shots with a semi-auto tippmann 98. Paintballs fired at 320 FPS ripped through the airwolf body, displaced the motor and collapsed the blades.

Test 2
We attaempted to have a gas powered RC helicopter sneak up on an entrenched position on painball field - craft was audible almost immediately
