Some boys just never get over decorating their bedroom with airplanes. John David built a Boeing 747 full sized flight simulator that replicates the jumbo jet cockpit. It recreates every switch and sound on a real 747. The simulator has an auto pilot, throttles and weather radar obtained off the net. It's made primarily from wood and cost about $30,000. The simulator has all the software to recreate take offs and landings from almost any airfield in the world.
