A very exciting and adventurous topic to choose for presentations(specially for school/college students).

2.  Introduction
 Technologies developed
 More Mysteries hovering

3.  A large US military base and one of the most secretive
places in the world.
 Location:- Situated in southern Nevada in Western
United States nearby Groom Lake.
 Also known by various names like Dreamland ,Groom
Lake and Homey airport.

the newer ones.

6.  Originally designed to be a safe place for the
president and rest of US government to stay in during
war times.
 To withstand a nuclear attack as it is almost entirely
underground.
 To develop and test the most advanced aircraft
projects and other technologies.

7.  Security force patrol the perimeter of the base in white

major specific projects are being worked on at Area 51.
They are:-
 Aurora project.
 Black Manta project.
 Electrochromatic Technology project.

10. Aurora - a top-secret hypersonic spyplane considered to
be faster than Mach10.
Uses Scramjet Engine that could take the aircraft into
space.
It is believed the plane is piloted, and not manually
controlled.

11.  Black Manta is a supersonic spyplane based on Stealth
Technology.
 Stealth Technology- It makes the aircraft ideally invisible
to radar ,infrared detection methods.
 It can operate at almost any altitude in the atmosphere.

12.  It is one of most rumored research projects.
 Based on devices which could make things invisible,
even human beings.
 The devices could possibly display what lies on the
other side of the material.
 Useful for spying and tracing suspicious things.

14. The first supposed UFO sighting was on 25th June 1947 in

provide any further
information. The base is
absent from Federal
publications and
inquiries to the
government regarding
the facility are rejected
for reasons of national
security.
