A company I used work for once bought a heap of spares from England amongst which were a heap of parts from the "Blue Eagles" flight line.
Most of us had never seen such new parts, there were several xmon's, the oldest being something less than 200 hours the youngest just 19.5 hours.
We popped the case apart for a look, the gears were all still blue from manufacture, so it must have been in their system, LOL. On the tags was the reason for removal, this really got us. "Removed due Intensive flying, Blue Eagles Aerobatic Team."
This we thought quite funny. The next morning as about nine of us took off in formation at daylight all mounted in '47's, we each tried to emulate "intensive flying," - pity there wasn't a camera about.
