Project HARP

This ugly rusty pipe could have solved the trouble with space deliveries in a fairly ecological way.
The prototype of the gun was constructed by the Americans in the jungles of Barbados and it even worked – in 1963 it fired a load 112 miles off of the surface of Earth. A record which still has not been beaten (and will probably remain like that for a while).
The shocking bit is that the US denied the opportunity of having a colossal gun, so Bull saw himself pushing his services to Saddam Hussein. The dictator liked the idea, financed smaller prototypes and was ready to build The Big Babylon – a gun more than 150 meters in length and 1 meter wide. Prior to that, though, he attacked Kuwait, which provoked Israel to send their special ops against the Iraqi weapon delivery people. That’s how Bull ended up with 5 bullets in the head and for understandable reasons – the project fell through.
