More millions down the tube.

The X-51A was slated to hit 4,000 mph and rip through the sky for a full 300 seconds Tuesday, and this is the second failure of the craft in two years.
WHOOO HOOO! - range 333 miles!
Though this test will see the X-51 dropped from beneath the wing of a B-52 at 50,000 feet over the Pacific,
experts hope the technology could*revolutionize air travel*on everything from to missiles, to manned aircraft.
Ummm....
http://en.wikipedia.org/wiki/Concorde
With only 20 aircraft built, their development represented a substantial economic loss, in addition to which Air France and British Airways (BA) were subsidised by their governments to buy them. As a result of the type’s only crash on 25 July 2000 and other factors, its retirement flight was on 26 November 2003.
http://en.wikipedia.org/wiki/Concorde#Retirement
On 10 April 2003, Air France and British Airways simultaneously announced that they would retire Concorde later that year.[141]
They cited low passenger numbers following the 25*July 2000 crash, the slump in air travel following 11*September 2001, and rising maintenance costs. Although Concorde was technologically advanced when introduced in the 1970s, 30*years later its analogue cockpit was dated. There had been little commercial pressure to upgrade Concorde due to a lack of competing aircraft, unlike other airliners of the same era such as the Boeing*747.[142] By its retirement, it was the last aircraft in British Airways' fleet that had a flight engineer; other aircraft, such as the modernised 747-400, had eliminated the role.[143]
…
It has been suggested that Concorde was not withdrawn for the reasons usually given but that it became apparent during the grounding of Concorde that
the airlines could make more revenue carrying first class passengers subsonically.[148] Rob Lewis suggested that the Air France retirement of its Concorde fleet was the result of a
conspiracy between Air France Chairman Jean-Cyril Spinetta and Airbus CEO Noel Forgeard, and stemmed as much from a fear of being found criminally liable under French law for future Concorde accidents as from simple economics.[149] A lack of commitment to Concorde from Director of Engineering Alan MacDonald was cited as having undermined BA’s resolve to continue operating Concorde.[150]

The only supersonic airliner in direct competition with Concorde was the Soviet Tupolev Tu-144, nicknamed "Concordski" by Western Europeans for its outward similarity to Concorde.[180] It had been alleged that Soviet espionage efforts had resulted in the theft of Concorde blueprints, ostensibly to assist in the design of the Tu-144.[181] As a result of a rushed development programme, the first Tu-144 prototype was substantially different from the preproduction machines, but both were cruder than Concorde. The Tu-144S had a significantly shorter range than Concorde, due to its low-bypass turbofan engines.[182] The aircraft had poor control at low speeds because of a simpler supersonic wing design; in addition the Tu-144 required parachutes to land while Concorde used anti-lock brakes.[183] The Tu-144 had two crashes, one at the 1973 Paris Air Show,[184][185] and another during a pre-delivery test flight in May 1978.[186][187]
Later production Tu-144 versions were more refined and competitive. They had retractable canards for better low-speed control, turbojet engines providing nearly the fuel efficiency and range of Concorde[188] and a top speed of Mach 2.35. Passenger service commenced in November 1977, but after the 1978 crash the aircraft was taken out of service. The aircraft had an inherently unsafe structural design as a consequence of an automated production method chosen in order to simplify and speed up manufacturing.[189]
The American designs, the Boeing 2707 and the Lockheed L-2000 were to have been larger, with seating for up to 300 people.[190][191] Running a few years behind Concorde, the Boeing 2707 was redesigned to a cropped delta layout; the extra cost of these changes helped to kill the project.[192] The operation of US military aircraft such as the XB-70 Valkyrie and B-58 Hustler had
shown that sonic booms were quite capable of reaching the ground,[193] and
the experience from the Oklahoma City sonic boom tests led to the same environmental concerns that hindered the commercial success of Concorde. The American government cancelled the project in 1971, after having spent more than $1*billion.[194]
The only other large supersonic aircraft comparable to Concorde are strategic bombers, principally the Russian Tupolev Tu-22, Tu-22M and Tu-160 and the American B-1 Lancer.[195]
