In a way this is possible, but woule take a whole lot of work and contributions to work. I would actually recomend a 737 of Aestreus to do the job, they lease them out. That way you would be able to make ALOT more stops on your 'freedom fighting' trip. Just get usual pilots to fly the damn thing (possibly Easyjet or Ryanair crew, as they are the cheapest) and just get John Trivolta to endorse it. Paint could be expensive, so why not leave the Aestreus titles on and make a 'hybrid' scheme, would sure as hell be popular by a.net photographers
. When it comes to catering use the cheapest of them all, Aviance. Also make it a full Economy layout using only the legal minimum seat pitch. Also charge the people wishing to fly on this aircraft HEAVILY. about the price of concordes final return journey to JFK
, but 4 X as expensive. Then all you have to do is get off-peak slot times at the airports you want to visit and leave less than an hour later so the prices of parking dont kill the trip.......
Then i recon you could do it, otherwise you may need to become the chancellor of the exchequer of the United Kingdom to use all tax funds. Mind you spending all the UK's tax funds on it is probably better than what its been spent on at the moment.
(p.s, for giving this advice i expect at least the jumpseat for the whole reound the world trip FREE).
