There’s reports on Twitter (X) that Rebecca Lobach the pilot of the Blackhawk worked as a White House aide in the Biden administration for the last two years and hadn’t flown during that time. True or not, I don’t know, but there are photos.
It is not uncommon for pilots to be assigned tours out of the cockpit. In the Navy, we called them squadron appreciation tours or flying appreciation tours. Prior to returning to a fleet squadron we undergo significant refresher training.
