#The revolution of military aircraft For anyone with a fascination for flying it is a surreal experience to stand in a hangar with five Bell 407 helicopters and not a single pilot in sight.
Welcome to the future of naval aviation fleets of unmanned helicopters flying on and off warships conducting missions as diverse as missile strikes

At the other extreme of the unmanned aircraft spectrum is the $80 million Northrop grumman built US NAVY Triton maritime surveillance aircraft.
Australia is set to buy up to seven of the jet aircraft to be based at Edinburgh RAAF base near Adelaide.
After that the aircraft will operate at five locations in so called orbits of four aircraft providing the US with constant global coverage of the oceans.

and Fire Scout and the most incredible of them all the X47-B unmanned combat jet that has landed already

marvel at the capacity of the latest unmanned flying systems. Lieutenant commander Selew is the Government Flight test Director for the Fire Scout MQ-8c at Point Mugu.
He is a PC-3 Orion pilot by trade and while he is prepared not to write the obituary for airborne pilots just yet he understands that unmanned systems are booming,
attractive and here to stay. He said chopper pilots were amazed by the performance of the unmanned machines. hey are more stable
and the feedback we get from the system is faster than from a pilot, Lt Commander Selew said.

#In Sweden Remote-control Airport Is A Reality As our plane touches down in Sundsvall Sweden the horizon is all snow and ice.
But this airport actually has two air traffic control centers. The second one is just a short walk from the airport runway.
Inside a ground-floor windowless room there's a display that looks exactly like what you'd see out of an air traffic control tower.
You can see the snowy runway you can see the trees you can even see a car pulling into the airport parking lot.
And the airport you're looking at isn't the one in Sundsvall. It's the one in Ornskoldsvik Sweden#about 105 miles away.
Ornskoldsvik is the first airport in the world to land passenger planes remotely. This summer an airport in Leesburg Va. will become the first American airport to use the new technology.
Erik Backman runs the remote airplane landing center in the town of Sundsvall. He explains that the town of Ornskoldsvik has a tiny airport
and it's expensive to keep air traffic controllers there who spend hours with no planes to land.
So they decided to have one team in Sundsvall that could handle both cities. The day you have one air traffic controller who can control two airports then you have some good benefits according to costs Backman says.
In Ornskoldsvik a set of cameras and microphones delivers a real-time image to Sundsvall. Of course new technology is notoriously glitchy.
And a problem landing an airplane is far more consequential than a laptop freezing up. Backman says when he saw the first mockup of this technology in 2004 he was dubious.
But a decade later they've been landing planes remotely for months without any major problems.
For the air traffic controller this is like airline pilots going from propeller to jet Henriksson says. It's a paradigm shift.
airplane numbers runway incursion warnings. You can zoom in or switch to an infrared view to see through thick fog or darkness.
And that might make this technology useful even for big crowded airports. Anders Carp is head of traffic management at Saab the Swedish defense
Airports in dangerous places could have a camera house instead of a control tower he says. The air traffic controllers could be a few
Back in the Sundsvall control center a plane descends toward the Ornskoldsvik runway. We watch it move across the screen.
The passengers#and even the pilot#have no idea whether they've been brought in for a landing from the tower they can see out their window or from this hidden remote center more than a 100 miles away
