• The metal found at the UFO crash of Rosewell 1947 was a man-made material called 'Nitinol'.

    Nitinol is a trade name taken from the elements it's composed of—nickel (Ni) and titanium (Ti)—and the scientific group that discovered it—the Naval Ordnance Laboratory (NOL). Under warm conditions the metal will always go back to it's original shape.

    The discovery of the shape-memory effect in general dates back to 1932, when Swedish chemist Arne Ölander, first observed the property in gold-cadmium alloys. The same effect was observed in Cu-Zn (brass) in the early 1950s.

    The earliest known combination of Titanium and Nickel reported in the scientific literature was in 1939 by two Europeans. However, this crude sample was a "by-product" of research entirely unrelated to the study of Nitinol. Its "memory metal" potential was not sought or noted. The scientists would have been unable to purify it.

    Though potential applications for Nitinol were immediately recognized, they would not entirely come to fruition due to the difficulty of melting, processing, and machining the alloy; Such efforts and financial challenges would not be overcome until the 1980s.

    1948 - 1958 saw a huge rise in the buying of Titanium for testing, especially on aircraft (roughly 2.5 billion in today's money).

    In 1980 a book called 'The Roswell Incident, written by Charles berlitz and William Elmore, was published claiming that an alien spacecraft was swapped out with a weather balloon; And the original alien spacecraft was taken to Ohio. Both men talked to as many as 90 witnesses during their investigation for the book; All claiming they witnessed UFOs or been to the crash site in 1947, or have even seen the alien bodies.

    (The laboratory contracted by Wright Patterson Air Force Base to perform these studies was Battelle Memorial Institute in Columbus, OH. It has been credibly reported that Wright Patterson Air Force Base was the very base where the Roswell UFO debris was flown after the crash.

    Recently obtained documents reveal that these studies for Wright Patterson were conducted at Battelle under the direction of Dr. Howard C. Cross. In the late 1940's, H.C Cross was Battelle's expert scientist in exotic metallurgy and Titanium alloy research.

    Curiously –although he was a research metallurgist- Cross was also Battelle’s "point person" in later studies on UFOs that Battelle conducted in the early 1950's for the U.S. Air Force's official UFO study, Project Bluebook. Cross is likely an author of Project Bluebook's still-missing Report Number 13. He is also the author of a strange letter from Battelle to Wright Patterson known as "The Pentacle" memo. Dr. Cross' historic role will be dailed in a forthcoming article.
    Founded in 1929, Battelle is engaged in research, development and commercialization of technological innovation. They specialize in materials science and engineering, life sciences, energy science and national security. Battelle contract operates many of our country's National Laboratories. This includes some of the U.S.'s most sensitive installations such as Oak Ridge, Lawrence Livermore and Brookhaven laboratories. Battelle is headquartered in proximity to Wright Patterson- and remains one of the nation's leading defense contractors.)

    There's also rumor that:
    A fake crashed UFO story was created in the early 1960s, in which Nitinol was used to try and convince certain players that the technology was from a crashed UFO. The Navy was actively engaged in using the UFO story to discredit the Air Force as part of an ongoing inter-service rivalry for funding, particularly acute between the end of WWII (1945) and the early phases of the Vietnam War (1955).

    So to recap:
    1929: Batelle Memorial Institute for technology was created
    1932: Shape-Memory Alloys were discovered
    1939: Nitinol was accidentally made in a crude form
    1945: Funding feud between the Air Force and Navy hits its highest peak
    late 1940s: Batelle hire's Dr.Howard C. Cross, a metallurgy
    1947: The Roswell crash happened
    1948: Titanium sales went up (largely for military aircraft) (product used in Nitinol)
    1949: Nitinol was perfected
    early 1950s: Dr.Cross starts research for Project Blue Book - Coined the term 'UFO'
    1955: The funding feud between the Air Force and Navy lowers
    1958: Sale of Titanium to the military lowers
    1961: Nitinol becomes commercially available to the public
    1960s: Rumors of a UFO (alien) crash at Roswell begin to spread
    1980s: A book called 'The Roswell Incident' spreads info claiming that an alien spacecraft was swapped with a weather balloon
    1994: The US Government comes out and admits it was a crashed weather balloon and the bodies found were crash test dummies
    2013: The US Government admits Area 51 exists

    1. Remember that 'UFO' in, 1950s and below, meant MILITARY Unidentified Flying Objects; Weapons and air craft from foreign countries and unknown groups.
    2. It wasn't until the 60s that the ALIEN UFO stories/conspiracies started coming out and the meaning of the term changed.

    The modern US Government has changed the term 'UFO' to the new term "UAP/AAV/UAS' because the Government decided that the term UFO is now related to 'silly' conspiracy theories about aliens, and can no longer be used in its original meaning; Which was MILITARY related.

    So, the US Government 'gave' the term UFO to the alien spacecraft conspiracy community, and came up with 3 new terms to describe serious military-related aerial phenomena.

    (UFO) - Unidentified Flying Object (Alien Spacecraft)
    (UAP) - Unidentified Aerial Phenomena
    (AAV) - Anomalous Aerial Vehicle
    (UAS) - Unidentified Aerial System

    It makes sense why they would admit it was a weather balloon in 1947, but they would NOT admit what type of material it was; Because Nitinol was not commercially available to the public until 1961; before then is was still being tested by the government for medical and military purposes.

    I also looked into the possibility of Mylar (BoPET), which was created by the DuPont Company, first commercially used and trademarked June 10, 1952; Mylar film was created in 1955, and the first Mylar balloon was made in the late 1970s. So, the years of it's creation and distribution don't predate 1947.
