And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Hawker Sea Hawk jets starting up their engines on a carrier
They're equipped with cartridge starters, a slow burning pyrotechnic cartridge is ignited and the combustion gases drive a turbine that is connected to the engine.
Al, it still looks like diesel tractor being started after a long cold weekend. My dad flew C46 and C47s and B17s in the war and he always bitched about starting them with shotgun cartridges when they were in a remote area with out AUX power. I was wondering why they smoked like that.
did a cold battery start on a EC121T in Norway back in the 1970's. had the FE do an oil dilution step on shutdown the night before. never realized before how difficult it was to cross all my fingers and toes before rotating the engine. Oh, it did start. great volumes of blue smoke flame and cylinder flatulence erupted with a withering blast of unburnt fuel and spitting engine oil blowing out the exhaust stacks of the bottom cylinders. extended idle period to get the oil warmed up. no dc ground power unit that operated was available at Bodo, and did that act only once. On top of that, the Nato base only had 100/130 avgas because the Russsian fuel tanker was stuck in ice. you would have had to have been there to understand the politics of the whole thing. the R3350-93A was easy to start as it had direct fuel injection and low tension ignition. did not like the primer. I always liked to start with the mixture controls instead of the primer except during a spit run. Un-pickeling an engine was the messiest thing to do. the sound and the smell of a round engine starting is something the brain always remembers.
Don't let the: OMFG "air-pollution global-warming freaks see this.

jets. hmph. suck and blow to fly. round engines and propellers screw their way thru the air.
