Los barcos del kaiser que fueron a la luna (continuación)

[Mendas]

Hace unas semanas para asombro de algunos y misma sorpresa de Beltza puse un post donde se comentaba que los propios barcos de la armada del Kaiser hundidos en Scapa Flow eran valiosísimos dado que su metal era anterior a la explosión de la primera bomba atómica y su metal se utilizaba para sensibles aparatos que iban a bordo de las naves espaciales:

Pues para que vea la gente que la historia no es una leyenda urbana y aunque la noticia es antigua, sirva este copia y pega que he extraido de internete:

"In 1995 it was announced that about 100 German WWII U-boats would be salvaged off the Scottish coast. These submarines were scuttled after the end of the war during Operation Deadlight, the disposal of the captured U-boat fleet. Because they were scuttled, there is no issue of them being war graves, as vessels sunk in combat would be. The reasons behind the salavge have been questioned, as raising a batch of U-boats doesn't seem to be a particularly economical way of getting scrap metal. In reality, the ship are not being salvaged to be cut up and melted down as ordinary scrap. These U-boats represent one of the last readily available sources of non-radioactive steel, and are being salvaged for that "clean" steel.

All steel made since the detonation of the first atom bomb in 1945 has contained tiny amounts of radioactivity. This is because the atmosphere now contains trace amounts of radioactivity. The steelmaking process involves the use of large amounts of air, which transfers the radioactivity to the steel. Instruments and equipment used for measuring radioactivity must be free from extra background radiation, so post-1945 "new" steel cannot be used for these purposes. Instead, pre-1945 "clean" steel is used. The steel is obtained from the scrapping of pre-1945 ships, and a considerable amount has been obtained from the German ships scuttled in Scapa Flow at the end of WWI. Obviously, steel obtained from these relatively limited sources is much more valuable than normal steel. The existing sources for "clean" steel have mostly dried up, so the salvage of the U-Boats is economically justifiable now. The submarines will not be melted down after salvage, rather, plates cut from the hulls will be used in their current form.

However, since the announcement of the salvage rights in 1995, everything has grown quiet, and there may be no actual salvage activity, now or in the future."

Luego no es una leyenda urbana ni un bulo. Increible pero cierto.
