Quotes from the National Geographic .com website:

“Engineers create a 360 degree model of the Phoenix landscape to estimate the size a UFO as described by a local eye witness.”

“Electromagnetic propulsion could send a spacecraft farther and faster into space than any propulsion system known to man.”
