so......they're broke, and they feel the need to put up this? 
Many projects startout like this. They need something ambitious and attractive to go out and show potential donors. Always aim high, if they get anywhere close to the money needed, the VEs (Value Engineers - aka penny pinchers - aka the bane to any designer's vision) will make/find a way to get it built within the budget.... and sometimes you just get lucky. Never know till ya try, maybe Bill Gates is a closet-BoB fanatic, pops up outa left field with a blank check and in less than 3 years we'll be reserving tickets to go visit the Gates Battle of Britain Beacon.
I think it is an absurd amount of money that could restore the entire RAF WW2 planeset back to flying condition!
The key words are private investment, people looking to make a return on an investment in the museum shop / cafe from the thousands of visitors per year. Call me a cynic but I just hate the idea that some suit is going to be using The Few as a money making venture.
I'm all for remembering what The Few achieved (I made an entire squadron based on them 
) But for me it is hearing those Spits, Hurricanes, lancs (no mossies / beaufighter 
) beating up the skies over Duxford on a sunny July afternoon. That is History brought back to life 
Not hanging from some ceiling in a fancy museum.
Ah, but relax my friend, this is again as I said an endevour to raise money for them through private investors. What are the odds that they'll get exactly the money needed for this project? Not good, honestly. On the plus side though, the odds of them getting the exact ammount are equal if not less than them actually raising slightly more than the money needed (so there's leftovers to go into other areas of the museum). Most likely though they won't get anywhere close... BUT!... lets say worse case scenario, they waise 10-20% of the funds. Thats still enough to pay for the design of this project pluss whatever is leftover gets redistributed to other areas of the museum. That's the great thing about this, even if it never gets built or comes close, it will raise some funds and awareness for the museum.
