Aluminium for passenger planes and titanium for fighter planes
Almost every country in the world now has airplanes.
Depends the type of aircraft, how many people are working on it and how long, and how advanced that company is in technology.. Now the planes are harder to build but now we have more technollogy. Before the planes were fairly simple to make, but they didn't have as much advanced technology.
Now we have airplanes and cars now
Well, if you want a certain TYPE of paper airplanes, and how many are there of that type, ask that. There is no real answer. A paper airplane is probably being made right now!

Long ago, the airplanes were used for the farmers but now, it's used for far away trips.
Airplanes are made of a variety of materials. The earliest ones were made of pine wood and canvas. Then steel braces and nylon. Airplanes now can be made out of anything from wood and canvas, to magnesium alloys and aluminum. Most private planes are made out of canvas-nylons and steel frames. Commercial jets can be made out of aluminum and new models are starting to use light weight magnesium frames to cut down on weight and improve fuel efficiency. The most common material used now is aluminum and steel alloys.
