Williams got 100 million for the cheap turbo fan no where

I worked there for 5.5 years, and I'm sure not going to praise them
for efficiency, but come on now, R (especially without the need or
expertise to D) is expensive. It is a hit or miss proposition. Chances
are really good that it will miss, and that is why very few businesses
will fund research.

Our efforts with rotary engines in aircraft are exactly the opposite:
as much D as possible, with a touch of hit or miss R when we have
no other choice. Neither way is optimal, but we got to start somewhere.

Yes David, but eclipse aviation is a private venture and the engine is not
cheap. Will they issue one share of stock to all us tax payers that funded 
the R&D? 

I see three serious problems right off the bat with the BWB.

A: The fuel locations is well aft of the CG.

B: What happens when you fly at 400 MPH into a 5000 FPM updraft
with all that wing area?

C: How do you evacuate 500 pax quickly in an emergency or crash?

Is one of these really better than two 777's and if so why?
