Ansett in Australia used a system call "combustor" to start their L-188's in remote areas. The combustor used compressed air bottles, all steel starters, injecting fuel into the starter air duct and igniting it. Flames would shoot out of a starter exhaust port in the engine cowl. Usually scare the hell out of someone that had not seen it before. Engine would spin up very fast.
