aphid_licker posted:Did they manage to make copies of the engines or was performance reduced? I understand that aircraft engines were just as bleeding edge metallurgically etc. for the time back then as they are today. The Tu-4's engines actually weren't reverse engineered things, they were developed independently (though I think they did copy the boost system). The Russians were pretty good at building giant radials. The metallurgy thing was a much bigger deal for the airframe; the Russians didn't have some of the cutting edge stuff Boeing had access to, but they were damned if they weren't going to copy that thing rivet for rivet, so instead of modifying the design they just lowered the strength requirements, because Russia.

Even better: In the 1980s, Russian's visited a Lockheed plant and applied a sticky substance to their shoes in order to collect metal shavings on the floor to get metallurgy from.

EDIT: The British GAVE the Soviets 20 jet engines that they reverse engineered. quote:The major problems inside MI5 concern its relationship with the former Prime Minister Harold Wilson. As the Minister responsible for trade in the Attlee Government, he attempted to increase exports to the USSR. He constantly ran up against United States Government opposition towards any growth in such trade. Wilson felt that the United States used the hysteria of the cold war to prevent Britain from increasing its trade with the USSR. His was not a position that was likely to be viewed with favour in MI5. In fact, there was near hysteria in MI5 when he was sent to the USSR to negotiate the sale of 20 advanced jet engines. Wilson was only a junior Minister carrying out a Cabinet decision, but from that point on he was viewed with suspicion by MI5 officers.

The Attlee government wanted to be friendly with the Soviets and decided the best way to do this was to sell them what was at that time the world's best jet engine; during the negotiations some Russians visited the RR plant and did the "metal shavings in shoe" trick. They PROMISED not to ever use them for military applications but you can probably imagine what was powering the MiG-15s that the UN had to fight over Korea

The Kennedy Space Center has a small piece of moon rock you can touch. It’s probably more germs than moon rock at this point but I still touched it.

Johnson space center in Houston has a moon rock you and all the other grody tourists can touch. Which I did, because it's loving cool. Also they have tons of moon rock and dust samples there you can look at through magnifiers, as well as descriptions of how they're different from earth rocks. Also redneck dads loudly proclaiming their ignorance with statements like "it's just a rock, who cares."

Both during the trip down and the trip back included surprising events affecting the performance of the 26-year-old two-seater.

The good part about working in an astronomy department is that we have a box of meteorites for public outreach. We've got two iron-nickel meteorites that must weigh at least 10-15 pounds each, plus cool poo poo like a pallasite. No Martian or lunar meteorites, though, unfortunately.

Around the time that the Curiosity rover landed on Mars, which was also not long after the recession, there were tons of posts on Facebook from people complaining about the waste of money. "We have enough problems at home! That money should be spent HERE ON EARTH! Give it to people who'll get us JOBS!!" (That was coincidentally about the last time I used Facebook.) So from that bit of data, I can conclude that a large number of Americans believe that NASA has no employees, benefits no one here on Earth, and every time we launch a rocket it's filled to the brim with bundles of cash to be shot into space.

Generally I want to know if it was a crap aircraft or not, but more specifically top speed, service ceiling, range, glaring mechanical issues, etc. It was an interwar design meant to be a bomber and a transport, with compromises that hurt both missions. E.g., two hydraulically powered turrets in the nose and tail that were undergunned (each with a single .303) that weighed the plane down when being used for transport. Range was 880 miles unless you installed the supplemental fuel tanks in the fuselage, which meant less bombs/cargo/pax. The wing was complex, the production was relocated and by the time the first ones arrived in 1939 (4 years after their first flight), they were already obsolete. Except for one unit in England that had them for two months in 1940, all saw service in Africa. As bombers they were replaced by the Wellington in 1940, and as transports by mid 1943 by Hudson IIIs and C-47s. Not actively bad, and better than the Valentia biplane that it was intended to replace, just not up to snuff.

Well yeah but I meant in a general sense of the whole crash. Looking closer at it, it looks like engine #1 was shut down and feathered before the crash, it’s the only prop undamaged.
