Fred Knudsen is a name I havent heard in a long while.
I didnt know he'd lost part of his foot though. I knew he'd had an ejection resulting in a broken back, the reason he was a fitness fanatic. He competed in triathlon events and cycled to the airport every day. Unfortunately I had only a few flights with him as my instructor but I learnt a lot from those flights and from talking to him. Im not 100% but surely he's passed away by now.
