the zero gravity plane

hello peoples

found out that there is a plane on which u go weightless. students who are to be scientist/astranouts with their teachers. the plane does a steep climb then curves in to a control free fall which provides about 20 seconds of weightlesness which seems like u r in space and then u fall back to normal possition. then there is also an incline where the body becomes very heavy, something like 400 pounds. and now not only scientists and teachers but you cal also on it by buying a ticket about somewhere between 3500--4000 dollars

here is a picture of a zero-gravity aircraft.
