Having flown in about 100 times (no, really!) it would be better t'other way up. The approach path is extended eastward depending on the number of planes coming in at one time. Many planes pass over Musselburgh and I don't think it'll be visible from them so it's those that pass over the pumping station at the east of the Prom that will get it. It won't be that visible from the island as people are mostly looking forward.
Errrrr...... just changed my mind! Looks great as you have it on the last pic!
http://www.flightradar24.com is a good way to see what really happens - Jess and I watch it lots - so interesting!
I think it's a Beezer of an idea, Paul. How about an image of a 99 alongside it? We could video the doing of it!
