Why do you suppose airplane window much smaller than bus windows?
to preserve pressure at higher altidudes.
Why do you suppose that airplane windows are smaller than bus windows?
I suppose they're smaller because they have to endure harsh and extended periods of change in pressure that windows on a bus don't. I suppose that to make an airplane window as large as a bus window that could endure the pressures, the window would have to be made out of either a very heavy material, or a very expensive material, which in both cases would make them prohibitive for installing on an airplane.
Why you suppose that airplane windows are smaller than bus windows?
Airplanes are often pressurized. A large window would be excessively difficult and expensive to make it strong enough to not blow out. So they use small windows on airplanes.
Why are airplane windows smaller than bus windows?
Aircraft are pressurized so that they can fly higher without the need for passengers to wear oxygen masks. They are generally pressurized to 5-8 psi. The force on an aircraft window approx. 12" x 12" would be 720 - 1152 lbs. If they had a bus-sized window (about 4 feet x 4 feet), the force on the window would be 11,520 - 18000 lbs.
Why are plane windows smaller than bus windows?
Airplane windows are smaller than bus windows because the cabin where the people sit is pressurized. This pressurization keeps a high enough pressure so that people in the airplane don't need to use oxygen masks. However, this pressurization equals about 9.0 pounds per square inch (PSI). This 9 pounds per square inch is a pressure that pushes outward on all parts of the airplane cabin. On metal this is not a problem, but with windows, made of a material that can be seen through, it's beneficial to keep this pressure low so that the window won't crack. If you think about the average airline window, it's about 120 square inches (a size of about 12 inches by 10 inches), and if each inch has 9 pounds of pressure pushing out on it, that equals (120 x 9 = 1080) 1,080 pounds of pressure on that one window. That's over half a ton! So, with a much larger window, like in a bus, that pressure would be too great and the window would shatter and blow out, making it very drafty inside the airplane! I hope this helps.
Is it safer to travel to Pennsylvania by bus than it is by airplane?
You can be concerned about safety when traveling. You will probably be safer flying in an airplane than traveling via bus. When events happen on airplanes, they can generate more media attention than if they had occurred on a bus. There is also the comfort factor to consider. You will arrive to your destination faster and more comfortable and rested by airplane.
Are bus bigger or smaller than pks?

How to Compare and contrast riding the bus and the airplane?
Other than speed, they are the same, one in the sky the other on the ground. Less security checkpoints to get on the bus.
Why airplane is better than bus?
In terms of pollution, a bus is far better than an aeroplane - aeroplanes emit the most amount of carbon dioxide per gallon of any vehicle. However, an aeroplane is far quicker than a bus, which is obviously a plus!
Which is material for bus window?
The material for most bus windows is toughened glassThe material for most bus windows is toughened glass
What are similarities between a bus and an airplane?
the difference is that one of them is on the ground and one in the air. and one has wings and one doesn't
