Ken May.
Nobody picked up on my previous. The story in brief: Basair looks like it evolved from Navair. Ken May, Navair Principal was the pilot who took a chap for a joyflight to the Hills district near Sydney and was somehow incapacitated to the extent the passenger took control and crashed the aircraft into his girlfriends house killing both on board. I don't recall any injuries on the ground. Just history to be aware of.
