Solent
I was transiting south to France and in receipt of a RAS from Farnborough. Very good service all the way down. "G-XXXX call Solent on ***.** they have your details". Very simple and good on Farnborough. HOWEVER Solent RT very busy and took 3 - 4 minutes to find space to call Solent. THEN I was told I had entered controlled airspace without clearance. Accurate (by about 250 metres according to GPS and DME show me at the edge) but as they had my details and I was well above any traffic conflict and I was heading 180 through their overhead I feel it was a little zealous to say the least. They also had my squaak so knew who I was and all relevant details. Not anyones fault but mine but would anyone (especially fro ATC) care to comment
