I absolutely agree with Genghis. I took a uni friend up once and he was very quiet and relaxed, in fact he dozed off during a one hour flight while I was having fun in a near new DR400. He didn't show much emotion on the ground afterwards either, but ever since then he says how much he enjoyed it and tells people about it when we are in the pub together. He can't be just saying that eiher because he came up again and often asks me if I have a spare seat going.
