| Where would the planes go
Posted: 8/12/2009 10:54:34 AM | Ok, heres a question........maybe not a good one, or a plausible one, but albiet a question none the less.....
If the earth exploded, or just vanished with no reason at all, What would happen to all the planes in the Air? if you know they didnt get hit by chunks of exploding earth........ They couldnt land anywhere ...... and they couldnt fall out of the sky because the sky would be gone.......... I guess they would just float in space for all eternity? .....¿ | |

i never knew planes breathed oxygen  | |

Posted: 8/12/2009 11:39:23 AM | In a sense, they do...
Pressurized commercial jetliners take outside air, compress it to levels that we can comfortably breathe, and feed it into the cabins. Without an outside source of air, there wouldn't be anything to send to the passengers. | |

Posted: 8/12/2009 12:02:43 PM | Well of course the passengers would all die soon...... but they would be floating in limbo forever untill the plane crashed on another planet in space......... And maybe then their bodys would decompose on that planet and in millions of years creat new life forms, since from what ieve hear life comes from life...... i dunno  | |

untill the plane crashed on another planet in space
Well if the had a good pilot there is no need to crash
just apply the air brakes..seen bugs bunny do it !! | |

Posted: 8/12/2009 3:02:43 PM | It would be a real mess. Becauseof the total vaccum of space, anything pressurized ,
including the people inside would probably explode in one fashion or another. Aircraft
arent designed for vaccum. The fuel tanks would rupture and the fuel would be ignited
and explode. The engine turbines would fly apart. This would most likely happen in
a few seconds. | |

Posted: 8/12/2009 5:40:53 PM | yes, you beat me to it Mr. Logic, the plane would continue to orbit the sun...just as debris from comets continues to orbit the sun (which is the cause for the meteor shower last nite and tonite)
however, the plane would not last a fraction of a second. Without an atmosphere, it would explode into pieces the instant the earth was gone. So it would really be bits of aircraft that would be rotating the sun.
But suppose, for some reason the airplane did not explode, and the people on it could live for awhile. With the earth gone, they would be in "orbit", which means they would be constantly accelerating toward the sun at freefall (just as we are now). Without earth's gravity they would feel weightless because of this freefall......just as astronauts do. | |

Posted: 8/12/2009 6:50:43 PM | Eh, I know where the planes would go. It is silly to think they'd just float in space.
After my space cruiser disintegrates the earth, I'd harvest the space around it for satellites of all kinds.
They go for quite a bit in the black market... on planet X... in outer space. Did I mention I have a space cruiser? | |

Posted: 8/12/2009 7:31:04 PM | a couple of older widows were flying to hawaii on a 747 to spend their inheritance. they ordered a glass of wine and as they toasted their deceased husband's generocity the captain came on the pa system.
"uh, ladies and gentlemen, we're having a problem with the number one engine and have to shut her down. nothing to be concerned about but it does mean we'll be arriving in honolulu a little later than planned."
the little old laddies just giggled and ordered another glass of wine. several glasses latter the captain came back on again,
"well folks, seems the number two engine just gave out on us. no worries now, this baby flies just fine on two engines. but it does mean we'll be even later getting to the gate."
the oldl ladies giggled again and ordered more wine. and once again as they were really feeling tipsy,
"ladies and gentlemen, its the captain again" this time there was definite concern etched into his voice. "the number three engine just caught fire. we got the fire out and the engine shut down. rest assured, this 747 will fly just fine on only one engine but we're really going to be late on arrival".
the one old lady looked at her freind giggling and said, "if we lose that last engine we'll be up here forever." | |

Posted: 8/12/2009 8:31:34 PM | I think it's obvious that the aliens who had just destroyed the earth would instantly beam all the passengers off said airplanes and get them ready for inevitable bum probing. They're fascinated with our bums you know.  | |

Posted: 8/12/2009 8:57:07 PM | | If the Earth disappeared, magically, the atmosphere would no longer be held by the Earth's gravity and would dissipate into space, along with the planes. They would remain in orbit around the sun in the vacuum of space where no one could hear you scream. | |

Posted: 8/12/2009 9:11:23 PM | No doubt the Vogons would be behind the Earth's disappearance! The inhabitants of the planes would be alright until the booze and coffee ran out and then would promptly, of course, explode. If the auotpilot was on in any of the aircraft, the plane would proceed to an alternate aiport, probably in an alternate universe. All the others would become fancy asteroids.
(Ha, and I thought I was no good at Physics! ) | |

Posted: 8/13/2009 8:35:33 AM | | I imagine without the Earth's gravity to curves the planes perspective of a straight line, and without gravity (or atmosphere) to provide a counter-force to acceleration. The plane would gain significant amounts of speed up until the point the oxygen in the engines is exhausted. In all likely hood a few of the planes would travel until they hit the Oort cloud, at which point they would most get smashed to pieces. | |

Without the earth's gravity to hold the atmosphere in place, it would probably dissipate rather quickly. So further acceleration would be quite limited.
In all likely hood a few of the planes would travel until they hit the Oort cloud, at which point they would most get smashed to pieces.
Not having enough time to accelerate for very long, they wouldn't gain enough kinetic energy to overcome the potential well of the sun. (I.e., they wouldn't attain enough speed to overcome the sun's pull of gravity so that they could even get close to the Oort cloud. And even if they did, the Oort cloud isn't some kind of physical "barrier". In fact, contrary to the popular notion that "outer space" is filled with all kinds of "stuff" (thanks to movies like "Star Trek"  ), even the Oort "cloud" is a term that must not be taken in our everyday literal sense. If you could go there and have a look, you wouldn't see hardly anything at all! (The "particles/objects" that make up that "cloud" are so sparse that you'd have to travel many many many miles to just go from one to another.) | |

Posted: 8/13/2009 12:24:47 PM | The modern airliner is pressurized to about 6000 feet. The plane would easily stay intact in the vacuum of space and the people would survive until the oxygen ran out. The only reason jet aircraft are not capable of traveling into space is the lack of oxygen for the engines.
There may be some bacteria in the cabin which could feed on the dead bodies of the passengers for as long as they last. After that, it would be a metal balloon without oxygen hulk populated by skeletons.
Naturally, the engines would flame out when the atmosphere disappeared but the plane and it's dead skeleton passengers would continue following the Earths orbit around the sun forever, or until something hits it. | |

If the earth was to explode the pressure wave would be enough to blow a plane to bits even if it was able to not be impacted with any debris.
Hypothetical conversation, If the plane some how was to survive both the shock wave and any debris.
Can you fly this plane, and land it?
Surely you can't be serious.
I am serious... and don't call me Shirley. | |

That's an interesting thought. I think the successful bacteria would be the ones that are already inside the bodies, though. Without the latent heat of the atmosphere, the planes and their contents would cool down quickly to the temperature of space (ca. 3 K). So bacteria that would be insulated within a body and consume enough energy to keep its enviornment within its habitable temperature would last longest.
That's a cheery though. Time for dinner yet?  | |

hmmmm. doubtful. an airliner is pressurized to roughly nine psid which will provide a six to seven thousand foot cabin it's true but the system requires continuous bleed air from the compressor stages of the engines to maintain that pressure differential. but the engines flamed out when the atmosphere left. a standard leak rate is about 3000 ft/min at 35,000 feet and would be explosive in a vaccume even with the outflow and safety valves slamed shut which they would do with a pressure loss. the passengers would be unconcious in seconds and completely toast in minutes. althought the crew would survive with there pressure masks, those little yellow dixie cups they call passenger oxygen masks will keep nobody alive. the air would rush out of your lungs before you could take a breath. | |

Posted: 8/13/2009 9:30:23 PM | Where would the planes go? That depends on the direction of thier flight at the time of earths departure. On object in motion tends to stay in motion unle some other force acts upon it. Planes are incapable of maneuvering in a vacume so the only force acting upon them would be thier initial velocity.  | |
