A Rare Drone Common Sense Outbreak, In Denmark

Last September, Denmark was gripped by a spate of drone sightings near airports. It’s familiar territory for Hackaday, as we reported on a similar drone panic saga at British airports back in the last decade. Back then the British police dragged their feet and hid behind secrecy laws for years to avoid admitting they overreacted, but it seems in Denmark they do things differently (Danish language, Google Translate link.).

The Danish police in Jutland have rolled back their report, and noted that a reported observation alone is not enough to confirm a drone was present. It’s not confirmed why they’ve taken this step, but we’ve been told that there’s been an effort within the drone community to identify possible aircraft flight paths which could have resulted in a false drone sighting at the times in question.

We welcome this correction, and hope that its important message travels widely. Of course it is the right thing to do for a police force to take drone reports seriously, but overreacting as the British police did is of little help. We commend the Danish police for taking this step, and we’re likely to trust any drone reports from them a little bit more in the future. If you’d like to read our plea for a sensible response at the time, it’s here.

Drones At Danish Airports, A Plea For Responsible Official Response

In Europe, where this is being written, and possibly further afield, news reports are again full of drone sightings closing airports. The reports have come from Scandinavia, in particular Denmark, where sightings have been logged across the country. It has been immediately suggested that the Russians might somehow be involved, something they deny, which adds a dangerous geopolitical edge to the story.

To us here at Hackaday, this is familiar territory. Back in the last decade, we covered the saga of British airports closing due to drone sightings. In that case, uninformed hysteria played a large part in the unfolding events, leading to further closures. The problem was that the official accounts did not seem credible. Eventually, after a lot of investigation and freedom of information requests by the British drone community, there was a shamefaced admission that there had never been any tangible evidence of a drone being involved.

Is An ADS-B Receiver The Solution For Drone Pilots?

Over the years here at Hackaday, we’ve covered a range of stories about the ongoing panic surrounding drone flights. From plastic bags reported as drone incidents through to airports closed with no evidence of drones being involved, it’s clear that drone fliers are an embattled group facing a legal and aeronautical establishment that seems to understand little about them or their craft.

It sometimes seems to be a no-win situation for fliers, but perhaps [XJet] has something which might improve matters. He’s published a video showing off a portable ADS-B receiver which could be used by drone pilots to check for any aircraft in the vicinity and perhaps more importantly allow the drone community to take the moral high ground when problems occur.

The receiver isn’t particularly special, being a Raspberry Pi with LCD screen and an RTL-SDR receiver in a nice 3D printed enclosure. He says he’ll be publishing all software and build details in due course. But it’s the accessibility which makes it such a good idea, instead of being a very expensive safety device it’s a receiver that could probably be made with a less powerful Pi for under $100.

There is of course a flaw in the plan, that not all pilots are concerned enough for their safety to fit an ADS-B transponder to their aircraft, and so are invisible to both the thus-equipped drone pilot and air traffic control alike. This puts the onus on pilots to consider ADS-B an essential, but from the drone flier’s point of view we’d consider that a spotter should be part of their group anyway.

Curious what the fuss is about? Let us take you on a journey.

The Gatwick Drone: Little By Little, The Story Continues To Unravel

If you remember the crazy events in the winter of 2018 as two airports were closed over reports of drone sightings, you might be interested to hear that there’s still a trickle of information about those happenings making it into the public domain as Freedom of Information responses.

Three Christmases ago the news media was gripped by a new menace, that of rogue drones terrorising aircraft. The UK’s Gatwick airport had been closed for several days following a spate of drone sightings, and authorities thundered about he dire punishments which would be visited upon the perpetrators when they were caught. A couple were arrested and later quietly released, and after a lot of fuss the story quietly disappeared.

Received Opinion had it that a drone had closed an airport, but drone enthusiasts, and Hackaday as a publication in their sphere, were asking awkward questions about why no tangible evidence of a drone ever having been present had appeared. Gradually the story unravelled with the police and aviation authorities quietly admitting that they had no evidence of a drone, and a dedicated band of drone enthusiasts has continues to pursue the truth about those few winter nights in 2018. The latest results chase up the possibility that the CAA might have received a description of the drone, and why when a fully functional drone detection system had been deployed and detected nothing they continued with the farce of closing the airport.

Perhaps the saddest thing about these and other revelations about the incident which have been teased from the authorities is that while they should fire up a scandal, it seems inevitable that they won’t. The police, the government, and the CAA have no desire to be reminded of their mishandling of the event, neither except for a rare bit of mild questioning do the media wish to be held to account for the execrable quality of their reporting. The couple who were wrongly arrested have not held back in their condemnation, but without the attention of any powerful vested interests it seems that some of the measures brought in as a response will never be questioned. All we can do is report any new developments in our little corner of the Internet, and of course keep you up to date with any fresh UK police drone paranoia.

The Gatwick Drone: Finally Someone Who Isn’t Us Asks Whether It Ever Really Existed

It’s taken two years, but finally it’s happened. Finally a respected national mass-media outlet has asked the question Hackaday were posing shortly after the event: what evidence was there that a drone was actually present in restricted airspace?

The Guardian newspaper in the UK is the outlet looking into the mystery of the Gatwick drone. It was the worldwide story of the moment around this time back in 2018 when the London airport closed down for several days in response to a series of drone reports. The assumption being put forward was that bad actors in the drone community were to blame, but there was significant disquiet in those ranks as the police and media story simply lacked credibility to anyone with knowledge of drones. At no point could they point to evidence that held water, the couple they arrested turned out to be innocent, and eventually a police officer admitted that there might not have been a drone after all. The damage had by then been done, as Received Opinion had it that irresponsible drone enthusiasts had put lives in danger and caused huge economic damage by closing an airport for several days.

The Guardian piece paints a fascinating and detailed picture of the events surrounding the investigation, by bringing the investigative journalism resources of a national newspaper into tracing and interviewing people involved from all sides. They talk to former Gatwick employees, off-the-record police officers with knowledge of the case, a drone specialist journalist, and the drone community including some of its members with significant professional experience in the world of aviation. It talks about the slow drip-feed of freedom of information requests revealing the machinations behind the scenes and furthermore the continuing lack of tangible proof of a drone. It’s very much worth a read, and we hope it will prompt further investigation of the events without the focus being on a non-existent drone.

We’d like to invite you to read Hackaday’s coverage from a few days after the event, and for an overview of the subject including the later Heathrow event, watch the CCCamp talk I presented on the topic in 2019. Then as now, our wish is for competent police investigations, responsible media reporting of drone stories, and credible official investigations of air proximity reports surrounding drones.

Justice For The Gatwick Two: The Final Chapter In The British Drone Panic Saga

At the end of 2018, a spate of drone sightings caused the temporary closure of London Gatwick Airport, and set in train a chain of events that were simultaneously baffling and comedic as the authorities struggled to keep up with both events and the ever widening gap in their knowledge of the subject.

One of the more inept actions of the Sussex Police was to respond by arresting the first local drone enthusiast they could find on Facebook, locking up a local couple for 36 hours and creating a media frenzy by announcing the apprehension of the villains before shamefacedly releasing them without charge.

In a final twist to the sorry saga, the couple have sued the force for wrongful arrest and false imprisonment, for which the cops have had to make a £200,000 ($250,117) payout including legal fees.

We reported extensively on the events surrounding the case 18 months ago, and then on a follow-up event at London Heathrow airport. The mass media at the time were full of the official line that drone hobbyists must be at fault, but then as now we were more interested in seeing some hard evidence. As we said then: Show us the drone.

So how has the new drone law progressed, since it was decided that Something Must Be Done? Enthusiasts have continued as before, and the multirotor community is as technically creative as ever. We were fortunate enough to host the Lets Drone Out podcast at MK Makerspace back in those halcyon days before the pandemic and see the state of the art in sub-250g craft, and with those and commercial offerings such as the DJI Mavic Mini all requiring no registration there is increasingly little need for an enthusiast to purchase a larger machine. The boost to the British drone industry we were promised has instead been a boost for the Chinese industry as we predicted, and of course we’re still waiting for the public inquiry into the whole mess. Something tells us Hell will freeze over first.

If you’d like the whole backstory in a convenient and entertaining video format, can we direct you to this talk at CCCamp 2019.

Gatwick Drone Incident: Police Still Clueless

Quietly released and speedily buried by Parliamentary wrangles over Brexit is the news that Sussex Police have exhausted all lines of inquiry  into the widely publicised drone sighting reports that caused London’s Gatwick Airport to be closed for several days last December. The county’s rozzers have ruled out 96 ‘people of interest’ and combed through 129 separate reports of drone activity, but admit that they are no closer to feeling any miscreant collars. There is no mention of either their claims at the time to have found drone wreckage, their earlier admissions that sightings might have been of police drones, or even that there might have been no drone involved at all.

Regular readers will know that we have reported extensively the sorry saga of official reactions to drone incidents, because we believe that major failings in reporting and investigation will accumulate to have an adverse effect on those many people in our community who fly multi-rotors. In today’s BBC report for example there is the assertion that 109 of the drone sightings came from “‘credible witnesses’ including a pilot and airport police” which while it sounds reassuring is we believe a dangerous route to follow because it implies that the quality of evidence is less important than its source. It is crucial to understand that multi-rotors are still a technology with which the vast majority of the population are still unfamiliar, and simply because a witness is a police officer or a pilot does not make them a drone expert whose evidence is above scrutiny.

Whichever stand you take on the drone sightings at Gatwick and in other places it is clear that Sussex Police do not emerge from this smelling of roses and that their investigation has been chaotic and inept from the start. We believe that there should be a public inquiry into the whole mess, so that those embarrassing parts of it which they and other agencies are so anxious to quietly forget can be subjected to scrutiny. We do not however expect this to happen any time soon.
