I have a pilot friend who flew as a First Officer on Martin 404's based in Floriday during the late 1970's.
One of their routes was to an airport in Cuba. He flew frequently with a very salty Captain known as
ROCKETMAN .
On one departure from Cuba, they loaded the pax, but the left starter failed.
They unloaded the pax, started the right engine and departed. After airborne they "airstarted" the left engine and returned to the airport.
The pax were then loaded and they returned to Florida.
