Why canít the signal be jammed? HMS Duncan warned Russian jets that they were flying a bit near and the ships radar could interfere with their electronics and fetch them down. (Sounded like a veiled threat to me).
As already highlighted, if it's flying a preprogrammed sortie, then there's no signal to jam...

Also, if it was genuinely that easy, it would be no more of an issue than a faulty tissue...

This is a completely unprecedented situation and the systems in place were perhaps not geared up to such an attack... I distinctly recall the initial impact of the liquid bomb threat in 2006, (I was working the preceding night shift... Ended up being allowed to leave four hours past my shift end when they finally allowed staff into work)... The threat had always been a possibility, but one so dastardly that no one had dared thought it possible, hence the apparent surprise.

Naivety is not a crime of neglect, rather an ilinformed perspective.

Ultimately sentinel drones will probably become the mandated norm for runway protection... Not too far removed from Terminator territory.

Apparently they're now reporting that two people have been arrested,hopefully they will prove to be the culprits and if so then made an example of.

Using jam technology while planes are trying to take off and land is probably not a great idea  :-\ safety issues
the airport should buy up the old stock of Russian heat seeking missiles to bring these drones down  :y

The terminology is a bit ambiguous... I take jamming to mean blocking a signal, and interference to confuse either the propulsion or GPS.

There was obviously summat going on with the temporary exclusion zone around the airfield.

Chapter 1, page 4 on the link I posted last night clearly defines the 3D space that must be kept clear around any runway ;)

Are they copycats or the ones doing both nights?


Example? Five years , out in two for good behaviour. One year for the battery changing assistant , suspended sentence. The drone operator will be in big demand in the nick. Just what they need to evade the long arm of the prison officer. ;D

Of course it can be jammed , technology is there just needs the authorisation.
Not really if its flying autonomously, as there is no signal to jam (assuming its being done maliciously by somebody with half an ounce of intelligence).  The Flight Controller (aka Autopilot) is pre-programmed with waypoints to fly to.  And that's also what makes it so hard to locate those responsible (assuming they don't want the drone back, else you just need to track where it lands and monitor that).

A £25 Flight Controller, and £7 GPS/compass loaded up with free open source software is all that is needed to fly autonomously.  And all multirotor drones have a flight controller of some description (too unstable to fly without), and the vast, vast majority have GPS capability.


Obviously, if its being manually flown, there will be a link, usually 2.4Ghz for short range (couple of km, so less likely in this case) or 900Mhz for long range (10km).  The trouble is, most links frequency hop to prevent interference - hence you can have a load of people flying together on the same frequency, with none of that tosh of sticking flags on you transmitter that you did in the old days - meaning you'd have to jam the whole frequency range and at high power.  Jamming 900Mhz would piss off the mobile networks and their customers, and potentially impact TV.  Jamming 2.4Ghz would piss off just about everyone.

I suspect the army's special equipment is organic, and just a better shot than the average flatfoot ;)
