I would like to incorporate it into my house.

Right there- many places like it, see if there is on nearby you. They are rather pricey though, considering they are scrap metal….

I want a picture of a really blue sky, and a few wispy clouds, but I want it mostly the sky. And I want an airplane near the top right, big enough to see but only taking up a small space. And I want a trail of clouds behind the airplane [the exhaust stuff that they let out].
Or as close as possible to this.
I don’t mind if it is photoshopped, but it has to look real.
Thankyouu!
Many thanks if you can find one.
Can you please send the link?
Thankyouu so much!

(I’ve asked this before, but I didn’t get a lot of answers)
I personally think it’s the picture of JA 123 on Wikipedia…it scared the CRAP out of me….
what do you think is the most frightening picture of a commercial airplane crash?
where on wikipedia is the pic on? the link please

For example if the window is missing or there is a small hole while the plane is in the air, will it cause people to be sucked out the window or the plane to crash? Please backup your answers with sources, I seen this on Mythbusters once but I can’t find any solid proof!
small hole or window, usually is not enough to bring down aircraft. unrestrained people can be sucked out, if the hole is big enough.
a Hawaiian based airline had a plane thet lost a huge section of the fuselage, it landed OK. it was about 10 years ago.
this is a pic of the aloha airlines plane,

when an airplane is flying how does the speed increase or decrease? does it work on the newtron’s 3rd law?
There are a lot of good answers here, Yes – both 1.increasing the throttle and 2. lowering the nose should increase airspeed,
but I think your question was subtley asking how low flying affects airspeed.
I think what you are alluding to is what is called "ground effect". When an airplane or helicopter is low enough (1/2 to 1 wingspan or less for an airplane or 1/2 rotor diameter for a helicopter),
ground effect produces more lift. You are able to have higher acceleration and airspeed as less energy is required for "lift". That is because the hard or liquid surface is pushing back at you, better than a volume of air can.
An aircraft’s top speed is actually likely to occur at a higher altitude where the air is thinner, but acceleration in ground effect, is greater than acceleration in level flight at 500 feet. Optimum altitudes are different for each airplane and found in the POH, which is like an owners manual, for each airplane, and are ususally thousands of feet above sea level.
As an aside, pilots have to be careful of getting overconfident with the effects of ground effect in high altitude flying, as airplanes will become airbourne at slower speeds than they will need to keep from wingstall once they get out of ground effect. Big Bear Airport, in California, at 6748 ft. / 2056.8 m, is a prime example http://www.bigbearcityairport.com/ . On a hot day the air is very thing and pilots can take off and then climb a bit into a stall and end up landing in the lake. Talk about soggy sandwiches!
Hovercraft rely on ground effect and could not normally fly higher. The Russians had huge planes that would only fly in ground effect above the water in the Caspian Sea http://en.wikipedia.org/wiki/Ekranoplan . I know of one experienced pilot that was ferrying a small twin engine airplane from Hawaii to California. When one engine went out, he descended to about 5 meters and flew on one engine the rest of the way, sometimes getting a little ocean spray.
P.S. Yes, Newton’s law is valid for this. F = ma
There are four forces operating on an aircraft:
Lift, Drag, Gravity, Thrust.
In ground effect, there is more lift because for every action, there is an equal and opposite reaction and pushing on the ground – which can’t move, gets more direct reaction than pushing on air particles that can move AND
2. The drag is less out higher altitudes, because of thinner air, there is less friction, so higher altitudes can be optimal.
Unfortunately the engine performs less well, unless it’s turbo charged or a jet, so at some point there will be an optimum altitude for speed.
