Odd lights over the Yorkshire Moors last Tuesday - swamp gas or something else?

Right, so I know how this is going to sound, but bear with me. Last Tuesday (14th, around 11:40pm) I was driving back from my mate Dave's place near Goathland - yes, the Heartbeat village, get your jokes in now - when I noticed three orange lights moving in a rough triangle formation over the moors to the north-east. Clear night, no wind to speak of, temperature around 4°C. I pulled over on the verge and watched for maybe six or seven minutes before they just... faded out one by one.

I'm not saying little green men, I'm really not. But I've lived near here for fifteen years and I know what Chinese lanterns look like, and I know what aircraft navigation lights look like. These weren't either. They moved too slowly for a conventional aircraft, held formation unnaturally well for lanterns, and there was absolutely no sound. My partner Sarah was in the car with me and she's probably the most sceptical person I've ever met - she's already drafted about four mundane explanations - but even she admitted she couldn't immediately place it.

I managed to get about forty seconds of footage on my mobile but as usual it looks like absolute nothing in the recording. A few bright blobs against black. Useless. I've included a rough sketch of the formation and approximate movement path - see attached image.

Has anyone else reported anything in that area recently? I've checked the MUFON database and found nothing for that date but I'm aware that's very US-centric. Would love to know if there's a prosaic explanation because it's been bothering me all week.

I can probably save everyone some time here: the MOD regularly runs night exercises out of RAF Fylingdales which is basically on your doorstep out there. Unlit or partially lit drones in formation aren't exactly unusual in that corridor, and they're specifically designed to be quiet. Not saying that's definitely it, but before we start phoning SETI I'd check if there were any NOTAMs issued for that area that evening. You can look them up retrospectively on the NATS website.

Also - and I say this as gently as possible - "it looked weird and I couldn't immediately identify it" is doing a lot of heavy lifting in this thread. An unidentified object is just that. Unidentified. Doesn't make it a craft from Zeta Reticuli.

Goathland area has a surprisingly decent history of reports actually. There was a cluster of sightings in 2003 and again in 2011 that got a brief mention in the Whitby Gazette if I recall correctly. The moors create their own atmospheric conditions - temperature inversions, methane from the peat bogs - which can do genuinely strange things to light. That said, three lights in stable triangular formation does push against the "natural phenomena" explanation a bit.

Did the triangle appear to be a rigid structure, or did the lights move independently but roughly maintain formation? That's quite an important distinction when it comes to ruling things in or out.

Swamp gas. Next question.

(Kidding, kidding. Genuinely interesting report, and good detail on the conditions. The fact your sceptical partner was also puzzled is worth noting - single-witness reports where the witness really wants to see something unusual are much easier to explain away. Will keep an eye on this thread.)

I drove through that exact stretch about a week before your sighting - nothing unusual on my end, but the moors at night do this thing where your eyes start playing tricks regardless. Darkness, isolation, the odd sheep moving in peripheral vision... the brain is absolutely desperate to impose patterns. I'm not dismissing you, just flagging that the context matters.

Did the triangle appear to be a rigid structure, or did the lights move independently but roughly maintain formation?

Good question and I've been thinking about this since I posted. Honestly? Independent movement, but with what felt like deliberate maintenance of spacing. If that makes sense. They'd drift slightly then correct. Which to me rules out a rigid craft but also makes lanterns seem even less likely because lanterns don't correct. Might just be my brain retroactively smoothing the memory though. Six days is a long time.

The MOD Fylingdales explanation is the most sensible one on offer, but I'd also check whether there were any military drone exercises listed under the Danger Areas for that night - D703 covers a fair chunk of the moors and it gets used more than people realise. Either way, cracking part of the country for this sort of thing. The moors have been producing weird reports since long before drones were invented, which is either very significant or a comment on how the human brain reacts to vast empty darkness. Probably both, honestly.
