Thread: No lpg bottles on choppers

the heights would be bloody extreme ! as altitude increase external pressure decreases. its like if you filled a helium balloon full and let it go then a few 1000 feet up it will expand till it ruptures. LPG cylinders are way tougher but the internal pressure at ground level is higher but theres 5 mm of steel and an over pressure valve fitted. seems a lot of bollocks to me but guess its up to the heli owner and hope its not more govt intervention
