It is fantastic. It doesn't look like all that much in the video, but when it moves over the ground and then just goes up in the air, it's amazing. It's not like being in a car because your body gets pushed down into the seat and you feel really heavy, it's a fantastic feeling.
I did a few trial lessons down in cornwall - one in a Piper PA28 and one in a cessna 152. I preferred the 152 because it was 'nippier' and you could see more of the scenery because it's a high-wing.
Now I've got a decent computer I ought to get the latest version of Microsoft Flight Sim, I'm just afraid that if I had that I'd never get anything done!
