As we celebrate the 100th anniversary of the Wright Brothers first flight, we can also look to the future of aviation.

Yahoo News says, "In the second century of flight, private companies will ferry tourists into space, personal flying machines will roam digital skyways and executive jets will make supersonic speed around the globe, aviation experts and scientists say.

"The next generation of airborne adventurers will carry colonists to the moon and to Mars, double-decker jetliners on Earth will load 1,000 passengers and small aircraft will depart and arrive on neighborhood runways with little or no help from their pilot-passengers."
