Someone must have done it, because in some of the old movies the pilot
yells out "wind 'er up" just before takeoff.
A starting method used for big engines (several 100 hp) involved a removable
handle with a gear train to a high speed flywheel. When the flywheel was
manually wound up to speed by ground crew the pilot engaged a clutch and
the power flowed back through the gear train to the crankshaft hopefully
starting the engine.
In the movie _The Great Escape_ James Garner and Donald Pleasance
steal a Luftwaffe trainer with that type of starter. I forget what it
is called.
Oh, and here is a bit of trivia. Donald Pleasance was an actual
POW during WWII. He was a crewman on a Lancaster (IIRC) that
was shot down.
