LIKE MANY World War I fighter pilots returning from Europe in 1919, Wesley Smith hoped to find a career that would keep him aloft. He had flown missions out of England during the war. Afterward he settled in Philadelphia and found work as a pilot for the brand new Aero Service Corporation, which had been founded in July of 1919 and was struggling to survive by delivering packages and taking passengers on joyrides. The company would have failed several times if Miss Mary K. Gibson, a Main Line socialite, had not given generously of her faith and fortune. During even the hardest times, Miss Gibson treated her pilots to handsome leather jackets and helmets.
Raised in Maybrook, her father’s sprawling, castellated mansion, she knew well the pride Philadelphia’s families took in their estates. She soon hit on the idea of charging families like the Stotesburys and du Ponts one hundred dollars for aerial views of their mansions.
