Impressive. This was an RC quadrotor demonstrating both remote assassination and kamikazi strike with blast payload killing capability.
Yet another reason why FAA issues NOTAM flight restrictions anywhere near VIPs that extend to all model airframes.
Here was the NOTAM for the recent VIP visit to Sandy Hook
“NOTAM/TFR has been issued for the area surrounding Windsor Locks and Newtown, CT for Sunday, 12/16 from 3:00p until 9:30p EST. The TFR is issued for security purposes to cover VIP movement in this area. Outdoor radio control model aircraft operations are prohibited within the 30nm circles for the specific times listed below. Control Line and Free Flight modelers should use discretion when operating within the TFR. Please note that TFRs are subject to change with very short notice. Check back often for the most current NOTAM/TFR information. Timely alerts are also available on the web or on your cell phone at: Twitter.com/amagov.”
I might add that this quadrotor could kill with kinetic force as well.
Imagine this unit with autonomous GPS waypoint navigation far removed from RC line-of-sight limitations able to operate in pitch black dead of night or foul weather and with infrared targeting.
I advocate public education as to what suspicious activities to report TO police as being far more urgent than activities OF police, although that is of concern, too.
Defensive measures around sensitive VIP locations and airports must anticipate terrorist, assassination and scorned lover attacks using mini-drones like this.
On the other hand the video at the link you provided could be fake, since only the barrel of an M4 without the receiver is supposed to be “firing” from the quadcopter...
See video down in the comments at this link:
Another thing that should have struck me immediately is that the payload of these minicopters is very low...too low to lift a semi-automatic rifle, IIRC.
The use of a quadcopter drone, perhaps with more modest firepower, is certainly well-presented as a thought experiment, for good or ill.
