What are the pros and cons of the airplane?

The speed of airplanes comes at a price:\nAirplanes whiz through the air and have to counter great frictional resistance. thus, they burn huge amounts of fuel. They are one of the major transportation polluters today. Also, for people living near airports, noise pollution is a major problem. Additionally, airplanes tie different countries together--this allows the spread of diseases, terrorists more easily-think SARS virus.

There are no real advantages, only perceived ones! \n\nThere isn't enough space to list all of the disadvantages.\n\nIf some one was to do an honest cost/benefit analysis, very few would own one.

i love to fly. i like planes better my fav is the b-2 stealth bomber

Make sure you have unlimited minutes on your cell unless you want hefty bills.  Check around for the cheapest air fare and see if you can find any good deals, the earlier you get your ticket, the cheaper usually.  There are some really great discounted airlines.  Try US 3000.  They may not fly to where you want though, the only downfall.

1.  At altitude, you'd freeze to death instantly upon exiting the aircraft.  The temp is typically -40F to -70F.   At normal cruise of 500 - 650 MPH, every bone in your body would be shattered when you hit the slipstream; most people's arms and legs would be ripped off by flailing injuries.  Think of all of the crushed and frozen arms, legs, and bodies with unopened parachutes attached hitting the ground at terminal velocity -- about 125 MPH.\n\n2.  Most accidents happen during the transition period of takeoff and landing.  You're too close to the ground for parachutes to be effective and there isn't enough time to get everyone out anyway.\n\n3.  There are no doors on an airliner that can be opened in flight, so there is no way to get out anyway.\n\n4.  Parachutes need to be donned before getting on the airplane.  You'd need to show up 5 hours before departure to get everyone suited up.  Connections would be 5 - 7 hours.\n\n5.  The bulk of the parachutes would require the airlines to remove half of the seats to make room.  Add the cost of parachute riggers and staff to help passengers put them on, and airfares would quadruple at least.\n\n6.  The typical airline passenger isn't trained in the use of a parachute; it would be akin to handing a 5-year-old a loaded AK-47.

I believe its something that should not be missed out. It will help find a cure for a lot of diseases and maybe enable people to replace lost organs or limbs.\n\nJust like any other technology it may be prone to abuse. But should that stop you from considering the benefits. \n\nThe airplane enabled people to travel safely globally yet was also used for war. Would you have wanted that the plane was never invented. This goes on for a lot of other technologies which define things that are standard today and can't do without.

ok well what do you want to know?\n\ndesigners use physics when they design airplanes.\nphysics allows us to determine how much lift a wing will produce and thus how much weight a plane will be able to carry.\nIt determines which materials and how strong they have to be to hold the plane together. \n\nphysics can also describe how the control surfaces (flaps and rudder) affect the plane and how big they have to be to control the plane safely.\n\nand that is just a start. physics is used in all aspects of designing and flying a plane.

My suggestion is don't be cheap and buy a real one.\nYou don't understand the positive and negative forces\non the frame and wing spar. It's not like building a kite\nand take it out for it's first flight. But If you think that you can\nbuild one and fly it with no experience with building or even\nflying one go right a head, I love it when I see some knuckle\nhead make the news, I just laugh my azz off.

minimal. \npower to weight ratio is significantly more important, as is wing design (the "lift" it can generate).\nplacement only concerns the weight distribution.

With thelong waits now prevalant for flights. A computer is a good pastime for games, checkng news and also checking flight info.

I've flown in the last few months and I enjoyed looking out the window during both takeoff and landing.  Well enjoyed it as much as possible while trying to entertain a baby :)

Earth is around, you know that. An aero plan has to fly around and it would be flying thousands of kilometers away from you.\n\n It would appear that the plane is flying so slowly. But if you see an aero plane that is flying on low altitude that would appear to be faster.\n\nSky is so wide, you can see larger area if you look further and further you can see more wide angle. \n\nIt is not same as if it is closer to you, the distance would be very small. If it is far distance is greater.

I'm no expert, but from what I've read:\nThe Bell SuperCobra has been a mainstay for years; a very good aircraft!  It's older, but still in use...that tells you something right there about it's adaptability and reliability.  The Apache is far more advanced...but also has far more reliability and technical issues.

air plane is not design for outerspace. From the word itself AIRPLANE, it need air and we all know there no air out in space.
