Thanks Scorpio. Didn't think I was being 'indignant' - but apologies if that's how it came across.
I sent an e-mail to ASTRA three weeks ago - no response for two weeks - so I rang the secretary listed on the web-site. I was told that person hadn't worked for ASTRA or Airservices for over a year! I was told that ASTRA is about to release a new version of their airspace management plans - that's why I was asking if anyone knew anything about ASTRA or what they're doing.
I'd hate to think they were about to launch yet another airspace plan without consultation [although what's new about that?!]. Is that why RHS is so quiet these days?
