I figured you were about 1,500 ft up and only got 2 orbits of Avebury from Lyneham airbase.
I took Notd & Greasemonkey up last year and they were blown away!
Notd didn't say a words for ages after she landed!

Are you going up again?
Let me know if you do and I'll take a pic of you!

Another friend, JJ, is planning a trip with me to do Arbour low, Castlerigg and Callanish!
He's been buzzing over to Carnac for lunch and getting some great photos!
