The Case for Antigravity:

"This presentation asks:
What is Gravity?
What is Anti-Gravity?
What evidence is there that technology, other than “conventional” aerospace technology exists which could be thought of as being “Anti-Gravity” or something attempting to control Gravity?

It then looks at:

Some History of Antigravity Research
Some of the Research of Nick Cook
The Hutchison Effect
Some Antigravity Experiments
Coral Castle (Florida)
Alleged Black Projects in the USA
Sightings of Flying Triangles
Hints of “New Technology” which have come from NASA

This is an interesting video that's worth a at least a glance. Are there already anti-gravity and electrogravitic devices and crafts already? Some would say yes, and have in fact existed for the better part of the 20th century, and that the Germans had a pretty good understanding in WWII. There are many rumors about the Germans having invented 'flying saucers' during the war.
