I dated Frank Whittle's granddaughter back in the early 70s. Imagine my amazement when, on our first date, I mentioned to her that a man named Whittle had invented the jet engine, and she replied, "he was my grandpa, Frank". Imagine my even greater amazement when she turned out to be a jet engine of another kind.
I'm not making this up....but it does make me wish I could time travel.
Cheers from NYC,
