On October 27, 1939, the US “Cash and Carry” law was signed allowing those nations at war with Germany to buy military equipment in the US so long as they took responsibility for having the equipment shipped from the US. On that day, the US aircraft industry received $220 million in new orders from abroad. Some of the new airplanes were flown by US pilots to the American side of the Canadian border and then dragged across the border by Canadian mules.
