- Mysterious drone swarms have been seen flying in colorado,nebraska and wyoming at night scenes December.A federal task force has been formed to investigate the drones'origin and purpose.
The philips country sheriff's office in colorado reported the first drones on 20 December.There have been hundreds of sightings since,some of group of drones flying in grid patterns.
Some observers assumed the drones were part of a military exercise.but the us air force has denied involvement.There is no avidence of malicious intent, although the drone operators are breaking us regulations governing flying at night.
The drones are described are resembling model aircraft with a wingspan of around 2 meters.None has been recovered or even photographed.similar drones are widely available online for a few hundred dollars.
Robert bunker of the us army war college's strategic studied instute in pennsylvania says the scale of operation suggest it is the work of an organisation such as a university , rather than a lone individual-assuming the drones actually exist.
The first question that the task force has to rule out is if we are not dealing with social media hype. Have these drone swarm sighings now turned into an urban legend?
Richard grill of uk company drone defence says that real drone sightings may have led to a number of false reports.
"People become hypersensitive after a scare,"he says."Everything with a flashing light will get reported as mystery drone."
Small drones are elusive though,and taking photos of them at night is virtually impossible.Even locating them on radder is difficult.
"Small drones have a low metel content,so a normal rader simply passes through says,"says GILL. "Detectingt them requires a special type of rader which usually has a range of just a few miles."
While the task force is said to be looking at getting a fix on a radio controller on the ground,GILL says it's best bet may be to bring one of the drones down, probably with a jammer.
