|Not the "drone" in question, but a design from Clemson U.|
For those of you following al Qaeda's system of asymmetric warfare, you've got to wonder if this is a AQ "proof of concept" of a possible UAV attack when you see a headline like this one from the NY Post, "Mystery ‘drone’ plane spotted near JFK":
The pilot told investigators the object was flying at about 1,800 feet and looked like “a black drone about a meter square, with helicopter rotors on the corners.”
You might as well ask how such an attack might work. Well, a goose can bring down an airplane:
Bird strikes, or the collision of an aircraft with an airborne bird, tend to happen when aircraft are close to the ground, which means just before landing or after take-off, when jet engines are turning at top speeds.You can take the concept from there.
The incidents are serious particularly when the birds, usually gulls, raptors and geese, are sucked into a jet engine and strike an engine fan blade. That impact displaces the blade such that it strikes another blade and a cascade can occur, resulting in engine failure.
You'll be pleased to note that "The Joint Terror Task Force is now probing the sighting of the mysterious flying object . . ."
Of course, it might just be some amateur out playing with his new toy.
Could you build a four rotor flying thingie? Heck, you can buy a small one here for about $100:
