Sadly it was always going to be a warbird too far IMHO. The fund raising that's needed to keep B-17G Sally B in the air each year is staggering, and the Vulcan makes that look like a p!ss in the ocean financially!
It was a valiant effort (no pun intended!:lol: ) but it's all come to fruition at a time were the economy is in freefall, and any potential sponsors will now be tightening their belts. It was always very doubtful that any major company would want to attach their name to a Cold War weapon of mass destruction anyway, no matter how good she looks asthetically.
It's all very sad, but until the 1990's it was run with the financial backing of the UK taxpayer through the RAF, the operating costs are simply too expensive for a private operator, even airlines are going down the toilet due to fuel costs etc.
