Is the air pressure in a flying airplane greater that outside the flying airplane?
In a commercial airliner flying at cruising altitude, the air pressure inside the airplane is considerably higher than the air pressure outside. The air pressure outside is too low for people to breathe comfortably, so the interior is pressurized.
What gas do people breathee in and what do they breathe out?
We breathe in oxygen and we breathe out carbon dioxide
Why are airplane doors and windows completely sealed?
Modern jet airplanes fly at high altitudes, where there is less air and therefore less oxygen. Aircraft cabins are pressurized so that pilots and passengers can have enough oxygen to breathe. There is a high air pressure inside the cabin because outside air (and oxygen) is forced into the cabin by the engines in order to pressurize the inside of the airplane, and this gives people enough oxygen to breathe. This is only possible because the airplane is sealed; if the windows and doors were open, the engines wouldn't be able to pressurize the cabin.

What can fly and has legs and does not breathe?
well a fly is a insect that flies and has legs. though it breaths. But this description vaguely reminds me of the greek monster tummus. Or an airplane, because the airplane has wings that allow it to lift off the ground and to so to speak "fly". It has legs, to help it land when it is descending from the air and making his landing at it's destination. Thirdly, the airplane is a man-made machine and therefor it does not breathe. I hope this answers your riddle.
