You're quite right, it is a high stress environment, but it's one I feel I would be able to handle (I'm worried about sounding like an overconfident accident-statistic-waiting-for-a-place-to-happen but I can't help it

). I have carried passengers before, and as it happens the passenger in question (

) does know a lot about aeroplanes (so I'm not worried about her being on board at all) ...
I understand the problems about the gliding clear rule, and appreciate the relative lack of fields should anything untoward occur... however it is something I've wanted to do for as long as I can remember, and something I think I could handle -- navigating from suitable landing field to suitable landing field would however be a significant task as you say....
The route in question would've involved quite a bit of flying before the CTR crossing -- which I was going to use to do all the usual patter, finishing the flight with a quick hop over london to do some sighteeing. I've been over the route from south to north (Biggin Hill -> Elstree) as pax before now...
Or am I being a total muppet?
