My dad was 75 when he was called in on this. It caused one hell of a shake up.
Hugh was in the same mould as my dad. Boffins… Both contributory scientists that weren’t just text book perfect in their roles, they wrote the books… (Not just a play on words, they did write them…).
He was accused by one of the investigators of being too old and they inferred he was past it…. and then dad dropped some undeniable evidence in the case. Next thing he knew they had asked him to fly overseas to help & discuss his findings… He said ‘I don’t think I could possibly do that journey… I’m far too old, apparently…‘
