Country:  | Okay but in that case what about the V-2 Rocket. It was not built out of any superior alloys and it easily crossed the sound barrier.

Country:  | well the SR-71 is actually made from steel, purely because nothing else practical can take the heat.......

Early V2's were found to have a tendancy to explode in flight before impact on decent. Study of recovered Peenemuende test V2's revealed that the forward hull was collapsing. An extra sheet of steel was added in the forward hull to prevent this. Also, the V2 didn't really have to "survive" it just had to hold up long enough to hit the ground, and it did not have to sustain supersonic speed very long.

The point is, it still reached Supersonic Speeds before it collapsed or blew up. You can say "It still blew up.", however it still reached supersonic speeds without any alloy's. Besides name any early advanced projects that did not have problems. We still see it today in the Osprey program.

| That is true. The DFS 346 should have an ESTIMATED (based on the wind tunnel values) top speed of Mach 2.2 at 65000ft. The actually flown speeds in the SU were much behind that. Only the top altitude of around 32000 m was confirmed (around 100.000 ft.). Speed was limited because of vibrations (probably caused by the shockwave of the stabilizer) of the tail. It could climb from 30000 ft. to 70.000 ft with a speed of 1100 Km/h IAS (ca. 680 mp/h). That is a bit suspect, since it would indicate a speed of around Mach 1.0 in this altitude (with an ucertainity because of the TAS). Drag was estimated to be very high at speeds of Mach 1.3 but there is no proof that such a Mach speed was reached (except in a dive by Ziese as mentioned above) in level speed.
He, I found in a soviet book from A. Galai the term license build for Tu-4! Interesting, or isnīt? (then it has to be propaganda by the soviets)

Country: | The Tu-4 was never lisensced built from what I have read. It was stolen.

Country:  | "Licence built" in this case means "Reverse engineered". They stole it. | |

Country:  | Does this mean that they stole the reactive and ceramic layered armour ideas for their tanks from the west too Adler. well I never, what a suprise

Country: | From what I can tell they pretty much stole everything in the beginning.
