An idea for a weapon I thought up

[Mustachio]

Rocket Propelled Silane Canister.

It is basically a modified RPG-7, but instead of rockets, it shoots canisters of Silane gas. Silane apparently ignites with oxygen and is highly toxic. If this could be fired from launcher via. Aircraft, it would kill people from explosion and gas. My idea is that it is mounted onto a Helicopter or similar, next to it is a mini-computer which zooms in 4x to the ground, where all heat signatures are depicted by a red cross. If you don't get what I mean, here's a badly edited picture:


Each Silane canister would be held in a long tube that holds 6 canisters, it would be loaded into the mounted gun, once loaded, a small disc at the bottom of the first canister to the side would spring out, it will have a hit detector under it, like a bullet does, and when pressed a explosion worthy enough of launching the canister out and downwards at a good speed, enough to smash the canister when in contact with the ground.

1.Helicopter holding them gets shot
2.The bullet hits the canister, creating a hole
3.Ignition
4.Helicopter burns up
5.??????
6.Profit!

I never said it was stable, the following scenario could happen to a minigun.
