Having visited Sywell on numerous occasions, I must say that my experience has always been positive with polite, friendly and helpful staff. That's one reason why I was particularly pleased to find that they have got permission for a hard runway.
The facilities are second to none, but of course being a visiting pilot I wouldn't know about internal politics.
I'd be intrigued to hear how a weather diversion culminated in "physical abuse" - presumably the assault was reported to the police? Sounds like far more than a 'bad hair day'.
