I received this pm some weeks ago which might help to explain.
I'm in ATC at LHR with friends in ATC at Farnborough.
After catching up with the thread I casually asked they had recently worked a Stearman....they asked me if it was the one flown by a woman, 'Spirit of something'?
I said yes, that's it.
They said 'oh my god, she is f***ing horrendous. She got lost both occasions I've worked her over the past week. She was holding a few miles south and started to wonder off towards Petersfield instead of joining the circuit at Farnborough.'
