Emergency order issued for Area 51 - ABC News

A reservoir pond surrounded by trees served as a recreational area one mile north of the base.

Other recreational facilities included a gymnasium, a movie theater, and a baseball diamond. Seven tanks were constructed, with a total capacity of 1,, gallons.

In January , the Federal Aviation Administration FAA expanded the restricted airspace in the vicinity of Groom Lake, and the lakebed became the center of a square-mile addition to restricted area RN.

The first A test aircraft was covertly trucked from Burbank on 26 February and arrived at Groom Lake on 28 February. Initially, all who were not connected with a test were herded into the mess hall before each takeoff.

This was soon dropped, as it disrupted activities and was impractical with the large number of flights.

Although Kelly Johnson had come to support the idea of drone reconnaissance, he opposed the development of an A drone, contending that the aircraft was too large and complex for such a conversion.

However, the Air Force agreed to fund the study of a high-speed, high-altitude drone aircraft in October By October , the drone's design had been finalized.

At the same time, the Q underwent a name change. To separate it from the other Abased projects, it was renamed the "D".

The "12" was reversed to "21". The first D was completed in the spring of by Lockheed. After four more months of checkouts and static tests, the aircraft was shipped to Groom Lake and reassembled.

It was to be carried by a two-seat derivative of the A, designated the "M". Difficulties were addressed throughout and at Groom Lake with various technical issues.

Captive flights showed unforeseen aerodynamic difficulties. By late January , more than a year after the first captive flight, everything seemed ready.

A second D flight was successful in April with the drone flying 1, miles, reaching Mach 3. An accident on 30 July with a fully fueled D, on a planned checkout flight suffered from an unstart of the drone after its separation, causing it to collide with the M launch aircraft.

The two crewmen ejected and landed in the ocean miles offshore. One crew member was picked up by a helicopter, but the other, having survived the aircraft breakup and ejection, drowned when sea water entered his pressure suit.

Kelly Johnson personally cancelled the entire program, having had serious doubts from the start of the feasibility.

A number of Ds had already been produced, and rather than scrapping the whole effort, Johnson again proposed to the Air Force that they be launched from a BH bomber.

By late summer of , the modification work to both the D now designated DB and the BHs were complete. The test program could now resume.

The test missions were flown out of Groom Lake, with the actual launches over the Pacific.

The first DB to be flown was Article , the prototype. The first attempt was made on 28 September , and ended in complete failure.

As the B was flying toward the launch point, the DB fell off the pylon. The BH gave a sharp lurch as the drone fell free.

The booster fired and was "quite a sight from the ground". The failure was traced to a stripped nut on the forward right attachment point on the pylon.

Several more tests were made, none of which met with success. However, the fact is that the resumptions of D tests took place against a changing reconnaissance background.

The A had finally been allowed to deploy, and the SR was soon to replace it. At the same time, new developments in reconnaissance satellite technology were nearing operation.

Up to this point, the limited number of satellites available restricted coverage to the Soviet Union.

A new generation of reconnaissance satellites could soon cover targets anywhere in the world. The satellites' resolution would be comparable to that of aircraft, but without the slightest political risk.

Time was running out for the Tagboard. Several more test flights, including two over China , were made from Beale AFB , California, in and , to varying degrees of success.

The remaining drones were transferred by a C-5A and placed in dead storage. The tooling used to build the DBs was ordered destroyed.

A second group arrived in Davis-Monthan is an open base, with public tours of the storage area at the time, so the odd-looking drones were soon spotted and photos began appearing in magazines.

Speculation about the DBs circulated within aviation circles for years, and it was not until that details of the Tagboard program were released.

That same year, the surviving DBs were released to museums. During the Cold War , one of the missions carried out by the United States was the test and evaluation of captured Soviet fighter aircraft.

Beginning in the late s, and for several decades, Area 51 played host to an assortment of Soviet-built aircraft.

ATIC personnel were sent anywhere where foreign aircraft could be found. The focus of Air Force Systems Command limited the use of the fighter as a tool with which to train the front line tactical fighter pilots.

Tactical Air Command selected its pilots primarily from the ranks of the Weapons School graduates. His aircraft was transferred to Groom Lake in late for study.

A joint Air Force-Navy team was assembled for a series of dogfight tests. Comparisons between the F-4 and the MiG indicated that, on the surface, they were evenly matched.

There were no clear advantages. The problem was not with the planes, but with the pilots flying them.

The pilots would not fly either plane to its limits. One of the Navy pilots was Marland W. He was an engineer and a Korean War veteran and had flown almost every navy aircraft.

When he flew against the MiG, he would outmaneuver it every time. The Air Force pilots would not go vertical in the MiG He had been watching as Townsend "waxed" the air force MiG pilots.

Cassidy climbed into the MiG and went up against Townsend's F This time the result was far different. Cassidy was willing to fight in the vertical, flying the plane to the point where it was buffeting, just above the stall.

Cassidy was able to get on the F-4's tail. After the flight, they realized the MiG turned better than the F-4 at lower speeds. The key was for the F-4 to keep its speed up.

An F-4 had defeated the MiG; the weakness of the Soviet plane had been found. Further test flights confirmed what was learned.

It was also clear that the MiG was a formidable enemy. United States pilots would have to fly much better than they had been to beat it. This would require a special school to teach advanced air combat techniques.

They lost their way and, believing they were over Lebanon, landed at the Betzet Landing Field in northern Israel. One version has it that they were led astray by an Arabic-speaking Israeli.

As in the earlier program, a small group of Air Force and Navy pilots conducted mock dogfights with the MiGs.

Very soon, the MiG's shortcomings became clear. It had an extremely simple, even crude, control system which lacked the power-boosted controls of American aircraft.

The F-4's twin engines were so powerful it could accelerate out of range of the MiG's guns in thirty seconds.

It was important for the F-4 to keep its distance from the MiG As long as the F-4 was one and a half miles from the MiG, it was outside the reach of the Soviet fighter's guns, but the MiG was within reach of the F-4's missiles.

To prevent any sightings, the airspace above the Groom Lake range was closed. On aeronautical maps, the exercise area was marked in red ink.

The forbidden zone became known as "Red Square". During the remainder of the Vietnam War , the Navy kill ratio climbed to 8.

In contrast, the Air Force rate improved only slightly to 2. The reason for this difference was Top Gun. The Navy had revitalized its air combat training, while the Air Force had stayed stagnant.

At Tonopah testing of foreign technology aircraft continued and expanded throughout the s and s. This involved testing Soviet tracking and missile control radar systems.

A complex of actual and replica Soviet-type threat systems began to grow around "Slater Lake", a mile northwest of the main base, along with an acquired Soviet "Barlock" search radar placed at Tonopah Air Force Station.

They were arranged to simulate a Soviet-style air defense complex. Larry D. The Lockheed Have Blue prototype stealth fighter a smaller proof-of-concept model of the F Nighthawk first flew at Groom in December Lockheed test pilots put the YF through its early paces.

On 15 October , Major Alton C. Whitley Jr. Although ideal for testing, Area 51 was not a suitable location for an operational group, so a new covert base had to be established for F operations.

The 6,foot runway was lengthened to 10, feet. Taxiways, a concrete apron, a large maintenance hangar, and a propane storage tank were added.

After finding a large scorpion in their offices, the testing team Designated "R Unit" adopted it as their mascot and dubbed themselves the "Baja Scorpions".

Testing of a series of ultra-secret prototypes continued at Area 51 until mid, when testing transitioned to the initial production of F stealth fighters.

The Fs were moved to and from Area 51 by C-5 during darkness to maintain security. The aircraft were defueled, disassembled, cradled, and then loaded aboard the C-5 at night, flown to Lockheed, and unloaded at night before reassembly and flight testing.

Groom performed radar profiling, F weapons testing, and training of the first group of frontline USAF F pilots. While the "Baja Scorpions" were working on the F, there was also another group at work in secrecy, known as "the Whalers" working on Tacit Blue.

A fly-by-wire technology demonstration aircraft with curved surfaces and composite material, to evade radar, it was a prototype, and never went into production.

As the Baja Scorpions tested the aircraft with functional check flights and L. On 17 May , the move of the th TG from Groom Lake to Tonopah was initiated, with the final components of the move completed in early The R-Unit was inactivated on 30 May The most basic area formula is the formula for the area of a rectangle.

Given a rectangle with length l and width w , the formula for the area is: [2] [20]. That is, the area of the rectangle is the length multiplied by the width.

The formula for the area of a rectangle follows directly from the basic properties of area, and is sometimes taken as a definition or axiom.

On the other hand, if geometry is developed before arithmetic , this formula can be used to define multiplication of real numbers.

Most other simple formulas for area follow from the method of dissection. This involves cutting a shape into pieces, whose areas must sum to the area of the original shape.

For an example, any parallelogram can be subdivided into a trapezoid and a right triangle , as shown in figure to the left.

If the triangle is moved to the other side of the trapezoid, then the resulting figure is a rectangle. It follows that the area of the parallelogram is the same as the area of the rectangle: [2].

However, the same parallelogram can also be cut along a diagonal into two congruent triangles, as shown in the figure to the right.

It follows that the area of each triangle is half the area of the parallelogram: [2]. Similar arguments can be used to find area formulas for the trapezoid [22] as well as more complicated polygons.

The formula for the area of a circle more properly called the area enclosed by a circle or the area of a disk is based on a similar method.

Given a circle of radius r , it is possible to partition the circle into sectors , as shown in the figure to the right. Each sector is approximately triangular in shape, and the sectors can be rearranged to form an approximate parallelogram.

Though the dissection used in this formula is only approximate, the error becomes smaller and smaller as the circle is partitioned into more and more sectors.

This argument is actually a simple application of the ideas of calculus. In ancient times, the method of exhaustion was used in a similar way to find the area of the circle, and this method is now recognized as a precursor to integral calculus.

Using modern methods, the area of a circle can be computed using a definite integral :. The formula for the area enclosed by an ellipse is related to the formula of a circle; for an ellipse with semi-major and semi-minor axes x and y the formula is: [2].

Most basic formulas for surface area can be obtained by cutting surfaces and flattening them out. For example, if the side surface of a cylinder or any prism is cut lengthwise, the surface can be flattened out into a rectangle.

Similarly, if a cut is made along the side of a cone , the side surface can be flattened out into a sector of a circle, and the resulting area computed.

The formula for the surface area of a sphere is more difficult to derive: because a sphere has nonzero Gaussian curvature , it cannot be flattened out.

The formula for the surface area of a sphere was first obtained by Archimedes in his work On the Sphere and Cylinder. The formula is: [6].

To find the bounded area between two quadratic functions , we subtract one from the other to write the difference as.

Define the discriminant of f x - g x as. By simplifying the integral formula between the graphs of two functions as given in the section above and using Vieta's formula , we can obtain [26] [27].

The above calculations show how to find the areas of many common shapes. The areas of irregular polygons can be calculated using the " Surveyor's formula ".

The isoperimetric inequality states that, for a closed curve of length L so the region it encloses has perimeter L and for area A of the region that it encloses,.

Thus a circle has the largest area of any closed figure with a given perimeter. For a circle, the ratio of the area to the circumference the term for the perimeter of a circle equals half the radius r.

The area of a regular polygon is half its perimeter times the apothem where the apothem is the distance from the center to the nearest point on any side.

Doubling the edge lengths of a polygon multiplies its area by four, which is two the ratio of the new to the old side length raised to the power of two the dimension of the space the polygon resides in.

But if the one-dimensional lengths of a fractal drawn in two dimensions are all doubled, the spatial content of the fractal scales by a power of two that is not necessarily an integer.

This power is called the fractal dimension of the fractal. There are an infinitude of lines that bisect the area of a triangle.

Three of them are the medians of the triangle which connect the sides' midpoints with the opposite vertices , and these are concurrent at the triangle's centroid ; indeed, they are the only area bisectors that go through the centroid.

Any line through a triangle that splits both the triangle's area and its perimeter in half goes through the triangle's incenter the center of its incircle.

There are either one, two, or three of these for any given triangle. All area bisectors of a circle or other ellipse go through the center, and any chords through the center bisect the area.

In the case of a circle they are the diameters of the circle. Given a wire contour, the surface of least area spanning "filling" it is a minimal surface.

Familiar examples include soap bubbles. The question of the filling area of the Riemannian circle remains open. A cyclic polygon one inscribed in a circle has the largest area of any polygon with a given number of sides of the same lengths.

A version of the isoperimetric inequality for triangles states that the triangle of greatest area among all those with a given perimeter is equilateral.

The triangle of largest area of all those inscribed in a given circle is equilateral; and the triangle of smallest area of all those circumscribed around a given circle is equilateral.
