25 seconds I thought it would be longer. The free-fall speed of the human body is 120mph. So, the aircraft has to dive and reach a vertical speed of 120mph. If you run the calculations with the a/c starting at 45,000 feet altitude, you would expect the aircraft could "fall" for 4 minutes. But, of course, you have to allow time for the aircraft to pull out of the dive and a little margin for safety. Then there are structural limitations on the aircraft. What is amazing is that the weight-less scenes in the movie "Apollo 13" were filmed using a "vomit comet". This required them to fly over 58,000 dives. The weightlessness is not caused by diving, but by flying upward into a curve (I believe it is called a hyperbolic curve). This curve essentially imitates what a body would do projected upward into a similar curve. I'm sure it's a great deal safer and less stressful (on body and plane) than any "dive" method.
Zero G conditions are achieved just before, during, and after the top of the above mentioned curve. For a informative diagram of this phenomena see the Web Link to the left.

How many times is the word vomit in the Bible?
The word "vomit" is in the King James Version of the Bible 8 times. It is in 8 verses. Please see the related link below.
What does retching mean?
Being sick (vomiting or trying to vomit).
What happens if you cry for 24 hrs?
You will most likely vomit, or have a very sore throat.
What is the name given to the disease that makes people vomit right after eating?
Bulimia is a psychological disorder that compels individuals to forcibly vomit their meals, in order to prevent gaining weight. Some physical diseases can also cause nausea and vomiting.
What does regurgitate mean?
It's akin to vomit i.e. to bring up food in the stomach back to the mouth cavity or out of the body entirely. Whereas humans vomit to get rid of bad food, other animals regurgitate as part of normal digestion. For example, cows 'chew the cud'.
Why it is important for astronauts to train in the Vomit Comet before going into space?
It is important cause they will vomit
What rhymes with grommet?
Some words that rhyme with "grommet" include "comet," "vomit," and "bonnet."
How do you not be sick in space?
Through intensive training. In fact, there is an old aircraft, a Comet, whose interior is cleared of seating and other stuff and its walls are cushioned. The aircraft climbs to a great height and then drops so that scientists inside are given a brief experience of weightlessness. You may be interested to know that this aircraft is known as the "vomit comet".
What is the nickname for the Zero G flight?
it is called vomit comet.
What rhymes with something that zooms through space and alcohol makes you do it?
comet-vomit
Can zero gravity be created in the laboratory?
No; creating zero gravity on Earth is not possible, unless the lab is at the center of the Planet or is free falling; like an aircraft accelerating towards the ground, namely the Vomit Comet. Stephen Hawking took that ride!
Why is it important for astronauts to train in vomit comet before gooing into space?
Astronaut candidates do "parabolic training" on a plane nicknamed the "Vomit Comet" (due to its tendency to induce motion sickness in passengers) so that they can experience weightlessness before being launched into space. If a potential astronauts is found to not be able to handle weightlessness, it's better to find that out before they actually get sent there for a long period of time. Also, weightless training gives them experience in how objects behave in zero-gee, so it's not a surprise when they get there.
How do fish vomit?
Fish vomit from changing water conditions or from eating something bad.
How did the vomit comet get its name?
The "Vomit Comet" is a nickname for the Zero Gravity Corporation's Boeing 727 aircraft, which creates weightlessness through parabolic flights. It got its name due to the intense forces and motion sickness experienced by some passengers during the flights, leading to occasional vomiting
What is the vomit comet?
A "vomit comet" is an aeroplane that briefly achieves zero G, allowing people and prospective astronauts to experience weightlessness.In general, 65 seconds of flight will achieve 25 seconds of weightlessness.Weightlessness produces nausea and sickness (vomit) in two out of three people and thus the aeroplane earns it's nickname.Zero Gravity Corporation in the US, will allow you - for a fee (Probably including a cleaning change) - to experience this.See related link for more information
Can or has anyone came up with the technology of weightlessness on Earth?
Flying in a parabolic arc is the best we can do presently. Astronauts have to take such training aboard the "Vomit Comet"
Real-life example of free fall?
Technically not real free-fall, but close enough to put the point across: -- jumping or diving from the high board at the pool -- the first several seconds of sky-diving -- the 'vomit comet' aircraft that flies parabolic arcs and gives its passengers, such as astronauts in training, several seconds of weightlessness.
