What maneuver must an airplane execute so that its occupants achieve Weightlessness for a period lasting up to a minute?

Kainantu

The maneuver begins by having the aircraft perform an aerobatic pattern which starts from level flight, and pitches up to approximately 45 degrees nose-high and wings level. As the airplane flies upward, it accelerates itself and everyone inside. Then, the engines are powered back and the airplane glides over the top of the arch with just enough power (jet thrust) to overcome air friction and drag. Everyone inside the airplane experiences the sensation of 'free-fall'. The body of the aircraft acts as a shield to prevent the passengers inside from experiencing the drag of the atmosphere. Passengers obtain approximately 28-30 seconds of microgravity during the pushover, which continues until the aircraft is about 30 degrees nose low. The aircraft is then slowly pulled out of the dive and when all people are safely on the padded floor, the acceleration is increased to about 1.8 gravities, for the pull-up to 45 degrees nose-high, and the maneuver is repeated. The maneuver requires a block of airspace from about 25,000 to about 35,000 feet. http://www.whereintheworld.co.uk/level3_pages/zerogravity_USA/d_zerogravity_USA.htm Dec 27 02, 3:17 AM

Who said, "Look Mummy, there's an airplane up in the sky"? In 1993 Meat Loaf edited what song from its 12 minute album version so that it runs 5:08 minutes as a single? Why is the refractory period so important? In "Die Another Day" a chopper falls out of an airplane but before it hits the ground the pilot starts it up and it takes off and doesn't crash. Is this physically possible?
