Answer 1

Every night after the close of business, there were scores of airplanes carrying paper checks from one city to the other. Had to spend the night once at a small hotel at the Greenville, NC airport and was shocked at the number of planes taking off and landing at night. Turns out Greenville was a regional center for check clearing.

Thanks for the awards. Makes not getting any sleep that night worth it.
