a few seconds
A long time!!
No... a flight cant stay in air without moving..even for a second....but some of the fighters and helicopters can stay in air for minutes or hours..
without the atmosphere the will stay on earth and without air there is no sound
Research suggests that flies can stay in the air for about one to two miles without rest. The average speed of a fly is about five miles per hour.
Forever
A person can live minutes without air.
Jets stay up in the air because they feel like it!!! hohohohoh
12 seconds
As long as they have flue to heat the balloon.
Without breathing, the world record is 22min With air bottles (scuba diver) or in a submarine you can of course stay longer. In a submarine when you have enough supplies, you can stay virtually forever under water.
It is fine to go as long as you want without farting. We fart while we are asleep as well so it's impossible for a person to hurt themselves by holding it in.
they can hold their breath for a long time but since they are mammals, if they stay down for to long without coming up for air they could drowned. so, sadly, yes, but there is a very small chance of it
