I blame ATC. Always and just because.
We had a pilot get his panties in a twist a few weeks ago because he got with a skydiving plane. Called the facility and insisted that there be an investigation.
Well,....turns out that when the controller asked him what his on-course direct destination would be, instead of staying on the vector he was on...he turned on course which put him together with the jumpers. Oops guess who got a PD?
And then there's the ASH pilot who got sent around two days in a row because the same Final trainee (not me!) ran him too tight...he rightfully called.
FTR after 4 weeks of Finals training I have 0 go arounds.
