Be interesting to get a map location to see how far he'd walked/how far from any paths he was found.

Like for Dr Mosely, optics on search teams drones, are they really poor ?, versus ubiquitous reaper/military equipment with some AI processing.
or, in this case was he found in a completely vegetated area with no possibility to see from above.

You tend to need to get really low and have a look from all angles in body searches (even in a lot of live searches)

Drones can be very good for finding live humans, especially at night, but even thermal imaging sensors still require LOS to the person and basically the higher you are the wider the area you might be able to see, but also the higher the chance you'll miss something if there is any variation in the ground level or vegetation.

There are all sorts of terrain where you can lose even an aircraft and potentially not find it until someone walks or climbs past something that looks odd and they check it out 25 years later.

Human bodies are quite small in the scheme of things, and very easily hidden by vegetation or land formations, hence the reason why police when they're doing a search in even light woodland or through fairly light brush will spread out so that they've got a line of people basically a meter apart actively trying to touch everything in front of them before they move forward another 30 centimetres.
There have been cases where a search for a missing person have gone past the body multiple times in mid density forest because they weren't able to do fingertip searching or were expecting the person to be able to call out/make a noise so were walking in close formation but not really thoroughly checking every single leaf (which is about what you have to do).

It’s just hard to imagine how he failed to make it a couple of km at the time.

Middle of the night, pitch black, drunk, tired. Not really. It’s also very easy to panic and lose your bearings, especially once your phone dies. There are plenty of places on those islands that aren’t lit at all.

Have you ever tried walking an unfamiliar area at night with no guide and over rough ground? It's not hard to imagine at all.

People have died less than 100 meters from help in the past because once you're off the route at night in the dark it is very easy to get disorientated and head in the wrong direction or injure yourself badly enough you can't carry on and that's if you're fully sober.

IIRC the advice for anyone who ever gets lost is basically stay on the road*, not wander off into the wilderness, which it sounds like is what he was trying to do.


*Or in remote areas with no roads, the river/streams as humans invariable build along almost any watercourse eventually.

Probably is possible to see from above and AI likely could solve this in future, the tech is basically already there right now.

You could have a small drone swarm systematically photograph the entire search radius fairly rapidly, maybe have an onboard classifier or indeed just transmit real-time images or video back for one on a more powerful local computer or one running in the cloud and save for heavy overgrowth you should be able to highlight a body. Especially so if still alive and using thermal imaging.

I didn’t think it was night time/dark. I thought he’d gone to catch the bus after pulling an all nighter

military capability probably as much for living humans and inanimate objects but their drones seem impressive (2mm?) https://youtu.be/CpLdL8ONEm4?t=789
combined with some AI to distinguish man made objects.

... but, I suppose even trumps conference was not deemed sufficiently risky to deploy such tech; IRD on the other hand I thought they have had a few mis-identifications of weapons.
