I may be getting my aircraft mixed up but I remember a post by a former crewman on the Wessex. He indicated that an explosive cartridge started the engines and that the propellant in the cartridges was very unstable. This individual recounted the number of times he would have to sit in the open door with his feet dangling out while he was holding the cartridges ready to dump them overboard if something caused them to sputter.
I’ll bet those guys that performed this function do not recall the Wessex with any degree of fondness.
But then again Fondness is in the eye of the beholder.
