I can’t understand why age is even relevant.
A pilot must meet certification standards and testing. Either you meet those standards, or you do not. If you meet those minimum standards, age is not relevant.
Perhaps this is why Federation Aeronautique Internationale and the National Aeronautics Association–the certifying officials for international and U.S. records–has no category for “youngest.” Those who believe it IS relevant have to go to unofficial sources–like Guiness Book of World Records–a source designed to adjudicate bar room bets. Interesting–according to Wikipedia, with falling sales of books in the internet age–Guiness went to the would-be record setters themselves to provide the revenue for the 50 staffers employed. They list the fee for researching and publishing the “record” as “between US$12,000 and $500,000 for help in finding good records to break as well as suggestions on how to do it…”
I have several FAI and NAA records myself. Perhaps I should look into setting a “record” as the “OLDEST” for Guiness–but first, I have to come up with their fee! (laugh)
