Well, I think she has a valid point.

Maybe God was chillin' in his lazy boy that day, sippin' a 40 oz., feeling kinda bored... and giggled to himself:

"I'm gonna snatch me up an airplane today. That'll sure mess with their heads for a bit."

Has anyone discussed the possibility that the plane never came back to ground but instead kept climbing, to the point it left earth's atmosphere? I know that a space shuttle has insane amounts of thrust/force/speed to get off the ground and into space, but could a plane, already traveling at 40,000 feet doing 500+mph pull the nose up and just keep going? What if that plane was so ing high that it just left the gravitational pull of the earth and went straight to heaven?!?

Just a thought.

From the interview...

Quote:
“Sean I think it’s incredibly arrogant for us as humble human beings to claim that we know how heaven works,” Palin responded, “How do you know there’s not a door to heaven in the sky between Malaysia and Vietnam?”
That's the best coffee-time bit of internet guff I've read in, well, forever. Brilliant!

Aircraft have what's called a 'performance ceiling' as to how high they can climb. This isn't a fixed number as things such as aircraft design, air pressure, weight of the aircraft, and temperature can all affect this.

It's simply impossible to drive through this without changing at least one of the above.... or just add a shit load of power like a rocket.

Anyway, even with a rocket there is a speed you need to reach before you can break the gravitational force of the earth, but I can't remember what that's called or what speed it is.

And speed.

Generally, the higher you go, the faster you need to go so you don't stall and fall out of the sky. But if you go faster than a critical limit, you'll lose lift and fall out of the sky. Neither of these are good things.

Mirfield and Marton provided very helpful posts around this, but is it possible?

... not after take off. The plane was hardly equiped with this sort of intention so how the plane somehow lost all of it's weight, increased the strength of it's design, and dramatically increased it's speed during flight I don't know.


Not even Felix Baumgartner got off the planet in a balloon. A full loaded 777 has no chance.

Re: Malaysian Airlines flight missing

Yeah, but you're all working on the idea that the plane went up.

What if it just went forward in a straight line?

The world is a ball, right? Well, if something goes forward in a straight line then sooner or later it's going to leave the atmosphere and go into space, no?

Like line x in this diagram:



See? All you clever buggers with your engineering degrees and maths o' levels, and you can't see the bleedin' obvious!

They should employ me to find it, you know. I reckon it's on the moon.

Well obviously, Isaac, if the plane is moving away from the Earth, the Earth's gravity is getting progressively weaker. Not only that, but the air is getting progressively thinner and thinner, reducing resistance and drag. That means that the plane gets faster and faster until it reaches escape velocity.

Seriously, I should work for NASA.

Re: Malaysian Airlines flight missing

Was wondering about the idea of the plane leaving the planet too ...... but found this:
Quote:
NASA: Why can't an airplane just fly into space?

Airplanes are able to fly because air moving under their wings is strong enough to hold them up... Large passenger planes can't fly much higher than about 12 kilometers (7.5 miles). The air is too thin above that altitude to hold the plane up....

To get a spacecraft to even the lowest Earth orbit requires a rocket. So how is a rocket different from an airplane? Rockets do not depend on air, even for burning their fuel.

Indeed, at 12km up gravity has been reduced by a whopping 0.2%

If you shrink earth to size of a basketball 12 km would be just 2/3 of the of the height of a dimple. Mount Everest is half the height of a dimple.

Earth diameter 12742 km
Basketball diameter 0.238 m
Basketball dimple height 0.35 mm

But if the mass remained the same, then the gravity would be horrendous!

The plane would have no chance of escaping like this one did.

But on the other hand, even then Earth would not become a black hole. Which means the plane can not just disappear.
