Surely someone from Clipgate is going?
If all else fails I'd get yourself and tent (auw 120lbs) down to Clipgate after school on Friday and badger everyone for a ride to Cranfield. I wouldn't leave Clipgate until the last aeroplane departs....
I wouldn't worry about getting back on Sunday. This isn't exactly GCSE big time for you.
In fact having never met your folks and hannah, I'd be inclined never to return

ps - Ed is a very nice, well mannered lad who is very enthusiastic about a career in aviation and if anyone can help him in his quest to reach Cranfield without him reverting to pedal-power, then the Rally will be richer for all of you!
