The Fat Man doing a JATO take-off. One of my favorites in Aviation. I got a chance to help repair one that had a JATO bottle break loose and went through the side of the airplane. I am glad I wasn't inside it when that happened.
I bet that was a pucker factor of 9+ on the sphincter scale.
Thank you for your service and sacrifice Anon, and thank you for the story.
God Bless You.
