Completely impossible, the plane has highest flight height to restrict, the practical ceiling of 737 is 12500 meters, empty guest of 320 is 12000 meters.
Increase as flight height, air density is in drop, oxygen content also is in drop. The plane is to carry fuel, engine changes heat energy to be kinetic energy through burning, offer thrust. Drop when aerobic content, engine thrust also is in drop.
At the same time although practical ceiling is apart from academic ceiling to still have certain space, but stem from safe consideration, also won't use academic ceiling.
In the meantime, want to break away from earthly gravitation, most at least must achieve the first cosmic, namely the speed of satellite of synchronism of our the top of head----7.9 kilometre every second just goes. The plane flies commonly speed is subsonic speed, 800 kilometre are controlled hourly, conversion comes over to also do not cross 222 meters of every seconds, be apart from the first cosmic difference became far, just be a family 3% be less than.
And our average flight height just is in aerosphere is bottom, 10 thousand meters of headroom are advection layer bottom nevertheless, want to fly off the earth, fly again even (36000-10) kilometre. This difference is not general big.
Break away from the earth not only suffer means of motivation of be confined to and oxygen, the pneumatic external form that still accepts plane of be confined to and collective structure bear ability. Although fly one day,function uses nuclear energy power, and can offer taller usable and successive thrust, still must add the airplane so thick add again thick. Exceeded ozonosphere radiate to come, arrived warm layer sometimes temperature can amount to more than 1000 Celsius, general metal can not bear.
If headroom is again tall, the radiate that has all sorts of universe ray, after these radiate are worth certainly more than, the body that meets pair of people causes great harm. Although fly,so function goes up, also nobody dare go up.
Certain level also is deciding pneumatic external form ceiling, can make at least of the plane enter the space resistance is greater, should achieve 7.9 kilometre the speed of every second, although air is again rare,also should overcome obstruction and gravity.
The place on put together is narrated, do not do, dare not do, can make it also should change a name to call space shuttle.
