  1. Bryan Swipe, I know that you will need to look through the webs of time to place me. I was on the Boeing 707 Inaugural Flight. A podcaster reached out to me and desired information on the flight. I just sent her your write up. I also sent her my book: More Than a Ticket Memoirs Flying with American Airlines from Props to Jets. She needs your brain. I enjoy everything you send out to the world to read. Thank you for your appreciation of history. I can send you the podcaster address.
