Trust me, they didn't just poor money into it. They ran some pretty amazing tests and learned alot from it. Though it was too bad that it didn't reach production phase. 4billion each wasn't that bad for the first two made. Considering a loaded F-22 raptor costs 22billion each setting the record for the most expensive aircraft ever produced. My dad's company Thales Air Traffic Management ( pronounced TAL-ICE)spent well over 70 million on the Universal all weather landing system "UWLS" and came out of it with what they considered "profitable" knowlage and they seemed to think it was worth the time/money. Now that's a French company saying that they thought that their money was worth the time on a product that never even rolled onto the production line/ and or produced a profit
, lol that's pretty rare. (ya I know I'm french and i'll go ahed and admit that we are picky when it comes to the check book [sm=greedy.gif] )
