During the 1920s, bush pilots needed to heat the oil in engines on their planes using an open flame torch called a blow pot.
Before take off in subzero temperatures, pilots placed the blow pot under the engine block, then covered the engine with a tarp to trap the heat.
Heating an engine with a blow pot was hazardous, and could take as long as two hours
Bush pilots also took this opportunity to warm themselves!
