Aircraft Oxygen

Will I reach the edge of space in a commercial aircraft if I just continue to climb,can you leave 'orbit'?

I mean simply going right through the rated 'ceiling' of an aircraft, and just going up up up. I'm sure I went extreamly high (8,000 ft? - can't recall) in a C152 once, but where does it all end? Commercial aircraft with loads of speed & power go much higher, so does the oxygen run out (failing the engines) before one can break the earth's gravity? Or do the engines stall and you return to earth (possibly at a rate of descent close to / greater than the Vne of the airframe)?

Crazy question, but my idle mind throws many of them at me each and everyday.

Yes, in a commercial aircraft, the aircraft's engines will run out of oxygen before you get into space. And there's no way that any commercial aircraft can carry enough velocity to enter orbit.

Some military aircraft can fly MUCH higher than commercial aircraft and get awfully close to the edge of space. The best example is the SR-71 Blackbird, which could reach an altitude of 85,000 feet. That's close to 17 miles up and the air is very thin there. The last SR-71 was retired in 1990 and one is displayed at the National Air and Space Museum at Dulles Airport, near Washington. A link for information on the SR-71 is posted below.

One other note on gravity: You can't really "break" Earth's gravity , as it is felt throughout space for millions of miles. After all, the moon is held in orbit by Earth's gravity (as well as some of its own). Therefore, getting outside the atmosphere means that you will fall back into it, and that is a very tricky proposition in any aircraft. Even the Space Shuttle can have serious problems re-entering the atmosphere.

Happy Warriors of WWII: The Aircraft Gunners $20.48 How can one forget watching B17s explode in midair with no possibility of survivors, or spinning down out of control as we tried to count the parachutes? Brings back memories of strong men throwing up at the end of the runway, before takeoff, from sheer apprehension and how these same guys became brave aircrew members when action started. Even today, the deafening clatter of our thirteen 50caliber machine guns, as enemy fighters go ripping through the formation, comes back often. The dull clunk of nearby flak bursts and the hail like sound of shrapnel hitting our airplane, then keeping my fingers crossed that no vital areas are damaged. I remember well, returning to our home base, several times, with gaping holes in the fuselage, and at least twice with one engine shut down and the other three overheating badly. The book title, Happy Warriors Of WWII comes from a commonly used expression to describe a group of free spirited, fearless, aircraft gunners, young men who loved to fly and were willing to face death almost daily. Death not only from enemy action, but also from the cold icy blasts sweeping through their aircraft while breathing life saving oxygen from tight fitting masks, that were always subject to freezing in the extreme cold. Off duty they enjoyed life to the fullest They were well known for their drunken bicycles. Many times our base had more gunners in the hospital from, self described, drunkenbicycle injuries than from combat wounds In this book, I try to give todays readers a real feeling of being there. So, pull on a pair of shoes and come walk in our footsteps. Author: Little, Terry J.

Do you really think you're safe on an aircraft that only provides oxygen.?

...Most of the time always no survivers- unless the plane reaches ground level. Do you think other proceedures should be implemented for your safety, parachutes etc...
Are the provided oxygen to make sure we are unfocus as well as disoriented?? is it safe and clean O2 we breathe.
Goddzilla, you said it loud and clear...
The Helmsman sometimes not at fault. Ways of preventing lost of lives is another subject matter/ you can never know what can go wrong, eh buddy.
Parachute etc, figure of spreeh, nimrods

So, go ride a bus, what do we care
