You'd effect a "load shift" within the plane, pretty much identical to what happens when cargo shift's within an airplane. First, we'd see the load (passengers of course) pressing the plane DOWN, but the actual amount of energy involved comes only from the passengers leg muscles -- not enough to generate even 1g, and planes are built to handle a LOT more G's than that. The fall to the cabin floor would be even less eventful, as everyone jumps more or less than everyone else. Assuming everyone jumped at the same time, you see a load shift that was peak. Everyone falling back to the cabin floor though will happen at different times, and thus the overall G-force of the fall is spread across time -- and will not spike all that much. So basically -- nothing of interest would happen. I think the greatest risk would be the flooring panels in the cabin. But let's toss in a little Tesla. If they all jumped over and over again in unison, at a frequency harmonic to something in the plane's structure, and if that jumping could gradually increase the amplitude of that harmonic, you might eventually see structural failure. This is pretty far fetched as planes run into this type of problem frequently and are built to avoid it. But it's remotely possible. However, the most grave scenario is if you get everyone to jump up and down at the same time over and over again, while singing the Starland Vocal Band's song, "Afternoon Delight" in tempo....
it will break....
From the altitude of the airplane when you jumped out.
Felix Baumgartner set the world record for fastest flight without an aircraft on October 14, 2012, when he jumped from an airplane 24-miles above the earth. He reached a speed of 833.9 miles-per-hour.
Man, this joke's odd. Me!
If everyone on Earth jumped at the same time, the impact would be very small and not noticeable. The Earth is so massive that the force of all the people jumping would not be enough to cause any significant movement or change.
Everyone jumped, and then they all sang together.
If everyone on Earth jumped at once, the impact would be very small and not noticeable. The Earth is so massive that the force of all the people jumping would be insignificant compared to the planet's size and mass. The Earth would not move or be affected in any significant way.
Albert Berry jumped from an airplane because he wanted to prove that a person could successfully parachute from a moving airplane. He was the first to perform this stunt in March of 1912.
The king is not in any royalty when jumped, he is then taken out of the game
D.B. Cooper jumped out of a Boeing 727 airplane with $200,000 cash
If everyone in the world jumped at the same time, the impact on the Earth would be very minimal. The combined force of all the people jumping would not be enough to significantly affect the Earth's rotation or orbit. The Earth is much larger and heavier than all the people on it, so the effect would be negligible.
Jeremy comes plummeting from the sky because he jumped out of an airplane without a parachute.
