WestAir grew out of STOLAir which flew Islanders and Trilanders. The initial Route was SFO - Santa Rosa and back.
I did the promo photography for them of a Trilander circling the SFO terminals and tower. I've got some great images from those days.
I was also doing the route acceptance flights for the FAA until they found out that I was also flying night cargo out of SFO to BUR and LAX in B-18s for Arabesco Airlines, the only Black owned airline in the US. I was told to pick one or the other. I chose Arabesco, the pay was better. It was single pilot, but they let us bring "Cargo Handlers" along. That made it "bearable".
