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….

Do all countries do this or is this strictly an Israeli thing?
lol, customs seem odd in other countries, we don’t do that in the UK, or in Australia, or in France, or Spain, or Africa, or Norway, or Ireland, or Germany, or Russia in my experience.

A person standing a certain distance from an airplane with four equally noisy jet engines is experiencing a sound level of 134 dB.What sound level would this person experience if the captain shut down all but one engine?
You need to divide the power level by 4, however you must use the logrithm rules as well as the fact that dB = 10*log base 10 (power) so
10 log( power / 4) = 10 log(power) – 10 log(4)
we already have 10 log(power) = 134 so we figure out that 10 log(4) = 6.02 So the dB power of 1 engine would be 134 – 6 = 128 dB

I want to travel to florida with my guitar.I dont want to store it in a baggage hold.
Actually many airlines will allow it on board if you make arrangements with them. It won’t go into the overhead but a flight attendant will stow it in some compartment.
If you do have to check it make sure it is tagged as fragile.

how does the thrust of a jet engine allow a jet airplane to travel compared to a propeller airplane?
the jet plane travels slower or must faster or is able to travel much farther or slightly faster?
how is composting an example of recycling [which of the following is correct? fruits & vegetables are composted to make a habitat for rodents/insects or paper waste is used to return carbon to plants or plant waste is turned into nutrient rich soil which is used to fertilize new plants or composting is not an example of recycling?
The jet engine has impellors inside it thatpull air into the engine through a channel called a venturi that tapers towards the center of the engine to a very small diameter. The force of air through the venturi creates large amounts of heat from friction (like a diesel engine), and what happens is the jet fuel is introduced just before the smallest part of the venturi, causing it to combust and create the energy, or "thrust" you mentioned. At the rear of the engine, there are dampers to restrict the output of the thrust, controlling the vehicle’s speed. The weight of the vehicle MUSt be less than the thrust that is put out by the engine, or the engine won’t have enough power to move the vehicle.
As far as recycling, no idea. Hoped the jet answer helps.

Are those little jet turbines that R/C guys put on model planes supposed to be oil lubricated or do they get there lubrication some other way?? And how does the fuel system on those little engines work?? I have seen one rev to 200,000 rpm and I was amazed that it could spin that fast without coming apart. I was just curious how those little engines work?
I’m really not sure. I built a small turbo-jet engine for a science fair project and i just added some castor oil to the fuel mixture and it worked fine up to about 15,000 RPMs. After that it was getting so hot that it was jsut burning the oil with the fuel which eventually led to by bearings fusing together. I really don’t know how it’s SUPPOSED to be done.
If you are interestied in this kind of stuff go to www.jet-man.com/actuel.html
It’s really interesting!

when the jets pulls g’s the vapor should come out everywhere and the sound is great like real life
like real life? no matter how good a game, its still a game, not life.
FSX has some great free addon planes with vapor when you pull Gs, good cockpit panels and sounds but you will have to find it all on the internet.

Jumbo the Jet is an interactive airplane that will fly children through learning their colors and shapes! There are two play modes – learn the colors and shapes, and find it. To play, simply insert the plastic shapes into their slots. The infrared remote control allows children to pilot the plane forward and backwards. Jumbo the Jet also plays four familiar nursery rhyme melodies! Remote Control Aiprlane 4 Colored Shapes For Sorting Realistic Sounds And Friendly Voice Blinking Lights Auto Shut-Off 5 AA batteries required. Recommended Age: 18 months – 3 years

According to Aviation weekly, there is between 8000 and 13,000 planes in the air at once, depending on the time of day.
Worldwide, air travel only accounts for 1.6% of human greenhouse gas emissions.
http://cait.wri.org/figures.php?page=World-FlowChart&view=100
However, due to the fact that they’re emitted higher up in the atmosphere, there’s actually an additional factor of 2.7 impact of airplane emissions on global warming.
http://www.sightline.org/daily_score/archive/2007/12/17/air-travel-how-much-global-warming
So overall, airplanes are currently responsible for about 4.3% of human global warming impact, which contrary to Jim’s claims below, are responsible for almost all of the current global warming.
