Oh very good point, didn't realize they were on a rejoin. I have no idea wtf he was doing then.
Never heard of it happening before. And if so, this would be much more prevalent with all the stud's panic stopping on rejoins. Hell, I can't even count how many times I would go idle/boards on a rejoin...probably every rejoin I did on my first handful of form flights. Multiply that by...all of UPT and if it was an issue with the PT6 then there would be T-6's falling out of the sky at a very rapid rate.
