The man cannon is design to hurl SWAT team members and other emergency personnel onto otherwise inaccessible rooftops. It consists of a forward-facing chair mounted on rails that point at an angle of up to 80°. Powered by compressed air, the “payload” would shoot up until the saddle reaches the end of the rails, at which point he would flail free skyward.

Seems like a great idea, but what if the SWAT guy has an extra clip in his pocket that shifts his weight…
