We're watching a movie in class and some students wonder how many g's a person can tolerate. The pilots on the show can tolerate 9 g's on an F-16.

the military answer and by the book: it depends on what direction one is experiencing acceleration.
1) in a forward or slowing direction the body can stand ALOT of G forces, that's because the blood is moving backwards or forwards. this is why astronauts can stand so many G's, it's pushing blood towards their back, not up or down.
2) without a G suit to assist, a pilot can stand about 4 or 5 positive G forces with reasonable assurance of not passing out. While i'm not aware of data on negative G forces while not suited, i would assume, by the way that a G suit works, that it's the same whether you've got one on or not
3) a pilot in a G-suit is assisted. the way a G Suit works is when the gyros detect high G turns, they fill the suit with air, squeezing the pilot's legs and thereby preventing the blood from pushing down so much into the pilot's legs. this means that a pilot can stand up to 9 positive G's. HOWEVER, a pilot can only stand up to 2 negative G's.
A Clarification: Positive G's are when you're pulling back on the stick, essentially turning in a direction which is "up" relative to the pilot. a negative G force is produced when you push down on the stick, turning in the direction relative "down" to the pilot

It depends on the person, but the newest aircraft have pilots that can stand slightly more than 9 Gs. Equipment like their seats and suits help out a lot. Without that equipment they would pass out at less Gs. There are unmanned missles that can pull 12 Gs or more.

Colonel John Stapp in 1954 sustained 46.2 g in a rocket sled, while conducting research on the effects of human deceleration. See Martin Voshell (2004), 'High Acceleration and the Human Body'.
Formula One race car driver David Purley survived an estimated 179.8 g in 1977 when he decelerated from 172 km·h−1 (107 mph) to 0 in a distance of 66 cm (26 inches) after his throttle got stuck wide open and he hit a wall.

In a F-16 Jet when they take a hard turn they withstand 9 G's but that is with assistance from their pressurized suit but i would say probably around 12-13 G's before you pass out.

Some have survived far greater- but conditioning is a major factor- check out Guinnessworldrecords.com to find-out.

Pilots wear g-suits that help them take the high g-forces. Without it they would black out or red out if it's negative g's

duration is the key in auto racing accidents drivers survive hundreds of G's but only for a few milliseconds

I believe about 10 g's...
