Hope to hell it continues and the scroats have been bagged and tagged.
I strongly suspect the scrotes have disappeared in to the night as quickly and quietly as they arrived. Sadly without a mistake by them or a tipoff they will be impossible to catch.

I would not be surprised at all if it was later revealed that there was one or more real or opportunistic, as-yet-suppressed extortion demands received during the crisis period.

And if not, then you can count on some arising in the near future.

This episode will be seen by some as a golden opportunity.

Oh please!! Firstly you don't need a "PhD in electronics" to create a viable multicopter with GPS and inertial flight control, FPV and some autonomy in the FCS. You don't even need education to basic bachelor's degree level - you can buy the parts off the shelf for small amounts of money, bolt them together and then spend a few hours consulting the numerous websites to find open-source code to adapt and generate your own custom control functions in arduino code (kids of 10 can and do manage this - I mentor STEM projects in schools where 12-year-old kids do robot projects of this level of complexity using off-the-shelf bits and adapted open-source code). If you want something large and with long persistence (more than half an hour) then the costs go up, but the sophistication doesn't. The sophistication only gets into the "professional" realm when you start wanting to make one that can be certified for commercial use in public airspace - then you need to be able to construct acceptable safety cases based on fault-tolerant/gracefully-degradant design and operation concepts to the satisfaction of the regulators. But that doesn't apply to the criminal/terrorist/hooligan/loony because they have no intention of operating legally anyway.

Secondly there is no such thing as a "Ph.D in electronics". A Ph.D is awarded for completing a piece of supervised research of a suitable depth that adds to the sum total of human knowledge. It's not a tutored course with exams in a specific subject - the whole point is that when you get to Ph.D level no one else can teach you because you are going beyond the boundary of current knowledge.

There have been suggestions that the scroates in this case may have been "eco-warriors" of the Plane-Stupid type. I have no idea whether these suggestions are informed or just speculative, but there's no particular reason why it couldn't be true. If so I suspect the eco-warriors may have stepped beyond the public's tolerance threshold this time.

Unrelated news, on BBC there was a display of a radio controlled eagle. It had lift props under each wing and one under the tail.

Seems ideal to me. Put up a couple if these raptors so the drone operators don't go to ground.

A drone to catch a drone would seem more cost effective than static sniper teams, helicopters or even Hercules. Probably easier to use something with similar flight characteristics.

And your point is?

From that site:
A PhD is a doctorate of philosophy based on mostly independent study. It typically takes a minimum of three years to a maximum of four years to complete full-time, or a minimum of five years to a maximum of six years when studied part-time. We also offer external PhDs for candidates who wish to study from their home country.

Under the guidance of your academic supervisor, you conduct unique research in your chosen field before submitting an extensive thesis of a publishable standard. A PhD thesis should cover all the requirements of an MPhil thesis, and make an original contribution to knowledge or understanding in the field you are investigating.

As your PhD progresses, you move through a series of progression points and review stages. This ensures that you are engaged in a process of research that will lead to the production of a high-quality thesis and that you are on track to complete this in the time available. Following submission of your PhD thesis, you have a viva voce (oral) examination assessed by experts in your field.


PhDs may be categorised into general areas, but that's just to allow it to be supervised by the appropriate faculty and professor. There is no "uber education in electronics" in a PhD - it would be research, not "education".

Yes - technically the name of the subject often doesn't appear on the PhD certificate (sometimes the title of the thesis does) - but universities do offer PhD programmes in particular subject areas, and everyone who has a PhD routinely talks about having a PhD in a subject - e.g. electronics, maths, biology etc.

Moreover, when a university offers a PhD programme in a particular subject - these days it often does include some tutored courses and exams in that subject area. This has been common in various countries for many years (e.g. USA and Canada). Also these days, getting to a level where "no one else can teach you" is a bit unrealistic for most PhDs - they are more like research apprenticeships. The key thing is that a PhD needs to make a "significant original contribution to knowledge".

I have a one, supervise PhD students, and have been an examiner for PhDs - so have more than a passing familiarity with this topic.

Is it worth dropping a line to dictionary writers and the Dept of Heducayshun I wonder ?......I only ask because the word "sardonic", not for the first time, seems to be missing from the vocabulary of many contributors .

However, thanks to the wealth of expertise available on JB, we now know all you need to construct a drone is a soldering iron, a crimping tool, some bodge tape and superglue to secure the big bits together... a couple of A4 batteries ....and some transistors....plus an account with ebay. !.

No educational attainment or development is required, just a "handy how to guide " in pictures .... a class full of rapt 7 year olds.....and bingo !

Time to make it a legal requirement to fit permanently active transponders to drones?
(Penalties to include incineration by [email protected] weapon, of both owner and craft.)

I just switched on Radio 4 just in time to catch the words "..at an address in Crawley, Sussex". I missed the first part and was wondering did this imply that Mr. Plod has foiund a door to bang on?

Legal remedy is unnecessary for those that abide by the law.

No law or requirement will stop the illegal use. The 'best' the law can do is enable the judiciary to met out sufficient sentences after the police can catch the perpetrators.

I am a little surprised the plod, or maybe the airport authority, did not call on the local model aircraft club.
"Go bust this thing up and we'll drop you two or three thousand." (or ten!)

The things those guys do with their aircraft are amazing and they could probably have put the thing down in a few minutes.

Looks like there is an opportunity there for someone.

Was more likely the story about the banker who bludgeoned an escort to death with a pestle at a flat in Crawley. He got convicted today.

The British army has deployed an anti-drone system developed by Israeli government owned electronics company Rafael Advanced Defense Systems Ltd. to protect London's Gatwick airport:-

Brilliant idea... oh but... hang on... I am sure that anyone using a drone for illegal activity will quickly learn how to deactivate said transponders, after all most modern drones have geo-fencing around locations such as airports and, if these sightings are accurate, that has not stopped these incidents from occurring

PPRuNe used to be full of mostly intelligent people in the aviation profession, however reading many of the posts in this thread I am beginning to wonder where they have all gone. Such a lot of nonsense posted, plus Gertrude and his usual boring habit of bringing politics and Brexit into every thread

"Over 90 percent of airports in the world are unprepared for drones," said the founder and chief executive of Fortem Technologies, which is testing a drone defense system on several American runways. - New York Times

I'm sure we'd all like to hear exactly what "the other 10%" are doing and how they are "prepared" for a drone incursion? An open source platform like Pixhawk supports predefined mission planning for autonomous flight without direct radio control. Signal jamming isn't effective in this case and that seems to be the basis of the Rafael system?
