That a/c (model) flew in the late sixties. Subtract the winglets, and one has the "Lifting Body" developed for the not yet built Shuttle. Further back in time google the "Goblin" a parasite fighter slung from the B-36. From the Fifties, before Sputnik, even. Use a critical eye, NASA is not even the primary on this 'project'. Even the B-2 is old hat, and proven to be an enormous loss of treasure, for a relocation of taxpayer dough into "Defense Contractor" pockets. Without a jaundiced eye, we are doomed to sign checks for these posers until your great grand children erase us from the history books, and for good reason.
The Blended Wing was developed for the F-16 in the late sixties, and has been operational for fourty years. Refrigerators for Eskimos??
