Turns out that this was not the case.
The oldest pilot(now in Guiness) is 99 years old and lives in the U.S. Unless of course, he just soloed recently. Who knows, maybe there is another as well.

Congrats to both on their accomplishments. Did meet one of them when part of the '90's(as in age) generation.
