Warplanes of Area 51-boeing
Stealth jets? Hypersonic bombers? What's really being developed at the military's most famous classified base? Take a closer look at the exotic aircraft the Air Force might be cooking up at Area 51.
blue book
Such interest forced the USAF to set up Project Blue Book to investigate the continuing sightings of unidentified flying objects. Essentially a public relations exercise, Blue Book ran until 1969 and its goal was to debunk UFO reports by any means necessary. One of their top investigators was Dr. J Allen Hynek, an astronomer from Ohio Universitytop secert nasa
Forty years ago, Jack Pickett, a publisher of American military magazines, was visiting MacDill AFB in Florida when he saw what appeared to be four flying saucers parked outside in a restricted area. They ranged in size from twenty to a hundred and nineteen feet in diameter and perfectly circular.Mars 69 (Photo : NASA)
Mars-69 521 et 522 sont deux orbiteurs de l'URSS qui, ayant atteint Mars, doivent déployer un module d'atterrissage vers la surface de la planète afin de photographier son environnement. Malheureusement, les deux sondes explosent au décollage à un mois d'intervalle. C'est la première tentative des Soviétiques de se servir de propulseurs à protons.
Solar cells
Why do we waste time drilling for oil and shovelling coal when there's a gigantic power station in the sky up above us, sending out clean, non-stop energy for free? The Sun, a seething ball of nuclear power, has enough fuel onboard to drive the Universe for another five billion years—and solar panels can turn this energy into an endless, convenient supply of electricity.
Les voyages spatiaux commerciaux
Le premier voyage commercial dans l’espace n’aura duré que quelques minutes le 21 juin 2004, mais le SpaceShipOne aura ouvert les portes d’une nouvelle aventure passionnante. SpaceShipOne est le premier avion (ou vaisseau spatial ?) commercial à atteindre l’espace, c’est à dire la frontière des 100 kilomètres d’altitude.L’intégralité du projet ($25 millions) a été financée par le milliardaire juif américain et co-fondateur de Microsoft, Paul Allen.
Before Man flew.
The chimpanzee "Ham" was the live test subject for the Mercury Redstone 2 flight on January 31, 1961. Here the 17-kg (37-pound) primate is fitted into a special "biopack" couch prior to flight. The 680-kilometer (420 statute miles) suborbital mission was a significant accomplishment in the American route to manned spaceflight.

We don’t know what these peculiar objects are,
but they certainly don’t look like anything
one would normally find at an airbase.
Note that what at first glance may appear
to be incorrect shadows are actually
enormous pits dug out of the earth.
And the three-sided pyramid is
perhaps the most intriguing of all,
especially since it appears to be made of dirt.
Sondes et Sensors d’intrusion de route( AREA 51)
La plupart des sondes ont été enlevées, et certainement remplacées par d’autres plus efficaces et moins vulnérables. Il reste encore d’anciennes sondes sur le domaine public, mais elles semblent inactives.Cet appareillage est un TSS-440 et un système d’écoute parasites (Un appareil semblable peut être vu a seulement quelques mètres à l'intérieur du grillage nord de Nellis AFB)
B2
Le bombardier stratégique Northrop B-2 Spirit est l'un des plus célèbres avions furtifs actuels des États-Unis.Son baptême du feu eut lieu durant la guerre du Kosovo où sur les 21 appareils, un pool de 9 participa à l'opération Allied Force, et un maximum de 6 simultanément.Le 24 mars 1999, deux B-2 lâchèrent leurs bombes sur des cibles yougoslaves au cours d'une mission de 31 heures.
CVSRF
The Crew-Vehicle Systems Research Facility (CVSRF) is an unparalleled national resource that supports NASA, the FAA, and many industry research programs. Designed to provide researchers with an environment where they can study how and why aviation errors occur, CVSRF stands out in the area of human factors research.
Space Shuttle Challenger
On January 28, 1986 the Space Shuttle Challenger was destroyed 73 seconds after liftoff due to a design problem with seals on the solid rocket boosters. 7 astronauts lost their lives, and NASA was subjected to several months of investigation by a Presidential Commission. The Commission’s Report revealed a lot of problems at NASA, mostly with communications between management and engineering staff.
“Akron”
In April of 1933, the United States Navy Rigid Airship “Akron” crashed off the coast of New Jersey. Seventy-three Navy airmen were lost in this horrifying disaster. The development of rigid airships and “blimps” ended in Europe at the end of the First World War. In the U.S. and Great Britain however, limited programs continued. The Akron was commissioned in 1929 and went into service on October 27, 1931. She was built at the U.S. Goodyear Zeppelin Corporation in Akron Ohio.

'This unmanned aerial vehicle (UAV) is 12 ft long, part aircraft and part spacecraft, will be dropped from the wing of a modified B-52 aircraft, boosted to nearly 100,000 feet altitude by a rocket after release over the Pacific Ocean to briefly fly under its own power at seven times the speed of sound, almost 5,000 mph.'Nanosat Launch Vehicle (NLV)
Ce lanceur est développé par la firme US Garvey Spacecraft Corporation en joint venture avec la California Launch Vehicle Education Initiative (CALVEIN) et la California State University, Long Beach (CSULB). Il vise le marché des nano satellites sur orbite basse pour le compte d'Universités et d'utilisateurs privés et petites industries.
