A starter breach failure away from home sorted out the men from the boys. The way round it was to start one engine using the good breach. Get the nav to stand in front of the running engine, unscrew the breach and then screw in the duff one.
He would then screw the good breach with a fresh cart into the other engine and Robert's your father's brother!
Letting go of the breach at the moment critique involved a LOT of paperwork.
