Electromagnetic Rays on a Plane

I'm not sure if I need to write a blog for Spring Break, but just in case...

I'm going on a trip to the mainland, and have an expected 20 hours of air-time there and back. Flying is a real hassel, though, because now they prohibit all kinds of liquids, sharp objects, and certain use of electronics. Especially while preparing to land, people in the plane can't use things like cell phones, radios, wireless stuff, and whatever. Not only because they could go flying when you touch down, but also because their electromagnetic waves can muff up all the sensitive equiment the airplane uses to fly and communicate with ground control, or else your plane might land on top of another. We learned about the lectromagnetics spectrum, and the waves that make up AM and FM radio. Cell phones and other wireless devices also run on radio waves, and if they are on the wrong frequency, say the one the plane is on, their communications will get messed up...Unless of course your plane allows it because it's equipment is all good, which is what a lot of planes are like today. Just don't be the guy who causes the plane to crash just so you could check on your streak...
