[quote:Inerrancia:MV8yMjY4MDYwXzM4NzYxMDYzXzg3QzBFNzMz] [quote:Anonymous Coward 42575720:MV8yMjY4MDYwXzM4NzUzMjI1X0U0RTJFMTM3] The first nuclear-propelled manmade object in space possibly occurred during the Pascal-B nuclear test. A 2,000 pound steel plate cap was blasted off the top of a nuclear test shaft at a speed of more than 41 miles per second. Dr. Brownlee, one of the test engineers, calculated that the nuclear explosion, combined with the specific design of the shaft, would accelerate the plate to six times escape velocity. The use of a subterranean shaft and nuclear device to propel an object to escape velocity has since been termed a "thunder well". Steel plates became successively larger and heavier. The Dark Knight is a 20 ton plate. [/quote] Let the guy alone, buddies... he's right about the f+++ng lid! "During the Pascal-B nuclear test, a 900-kilogram (2,000 lb) steel plate cap (a piece of armor plate) was blasted off the top of a test shaft at a speed of more than 66 kilometres per second (41 mi/s). Before the test, experimental designer Dr. Brownlee had performed a highly approximate calculation that suggested that the nuclear explosion, combined with the specific design of the shaft, would accelerate the plate to six times escape velocity. The plate was never found, but Dr. Brownlee believes that the plate never left the atmosphere (it may even have been vaporized by compression heating of the atmosphere due to its high speed). The calculated velocity was sufficiently interesting that the crew trained a high-speed camera on the plate, which unfortunately only appeared in one frame, but this nevertheless gave a very high lower bound for the speed. After the event, Dr. Robert R. Brownlee described the best estimate of the cover's speed from the photographic evidence as "going like a bat out of hell!" The use of a subterranean shaft and nuclear device to propel an object to escape velocity has since been termed a "thunder well". This incident was reputedly used as part of the technical justification for the Orion project for possible use of nuclear blasts for outer-space propulsion." http://en.wikipedia.org/wiki/Operation_Plumbbob [youtube]http://www.youtube.com/watch?v=MYQOfs98ljM[/youtube] Crazy, bizarre, cool stuff...! [b]BUT[/b] it happened in 1957, [b]AFTER[/b] the first informations on the Dark Knight...(lol) [/quote]
This is old stuff from the 50s, but it seems it remains still as a modern enigma...
If the historic rumor is true, we are talking about a secret (and pioneer) space power, or an "alien" surveillance, or an "alien" probe, or VALIS or about what?
Sceptics claim this is simply some astronautical debris, but yet nobody has identified it...
