how much time stand still with air still airplane
the airplane will fly farther. This is due to the fact that both the airplane and the hot air balloon use fuel. Also because the hot air balloon only means of movement is wind, While an airplane use jet propulsion. This allows the airplane to travel in any direction
Gliders use no energy but they do use an airplane to tow it into the air.
An airplane or a helicopter
No it can't go out because there is no much air.
Yes, but you can't use it.
i saw a delicate airplane soar through the air
That's true for the airplane's wings, when the airplane is flying upright.
The percentage of Oxygen in the air is the same in airplane as it is outside the airplane. The only difference is the pressure levels. If the pressure drops too much then the total amount of Oxygen will be insufficient for you to breath and you will pass out. The airplane only carries oxygen for use in emergency and is dispensed in the oxygen masks of the crew and passengers. Maybe your Question is asking what the total volume of oxygen is available in a pressurized airplane. I don't know that.
Atmospheric pressure is caused by the weight of air above the measurement point. At 30,000 feet in the sky, the air pressure on the outside of the airplane will be much lower than it was nearer the ground.
The First Airplane Lasted 12 seconds in the air.
