Amazing what a small world this is. I was with a friend at the Intrepid Museum on Saturday, and there was a Piasecki H-25 Retriever.
Thought this was a coincidence in name though didn't think anything of it again, until I met with a friend/colleague this week, and it turns out that was his father!
Reading his obituary it turns out he was also the first helicopter pilot to get an helicopter license without having a fixed wing license.
An interesting man indeed.
