Here is annother way to disable plain, freely available drones - sounds like a joke at first but the effort is serious: Let an eagle catch it! [from The NY Times]

Senators Jack Reed and Roger Wicker have an op-ed in the Washington Post about the danger of military's insufficient drone detection capabilities. https://www.washingtonpost.com/opinions/2024/04/22/drone-attacks-us-troops/

However, I'd propose that this rule is observed: The exhibits should be solvable, at least in theory.

I'm not familiar with these, but I thought it would be educational for readers around here. My example was WAY too easy but it has served quite well as clickbait :-) I like these rules. However, the exhibits should at least be solvable in theory. Also, for educational purposes, the leading...

I'm proposing a thread (or maybe a dedicated subforum) where photos can be posted with the task to geolocate them, for educational and training purposes, and yes. also for fun :cool: Also possible are variants where e.g. the time of a photo is hidden and must be determined. As a fairly easy...

A glider IS a plane !!! I demand satisfaction !!! The canopy jettison lever indicates one of the Schleicher models.

User @greg51361570 on Twitter just posted a reference which refers to the "chemical agents, like pesticides" mentioned in that article. For completeness sake, this should be in the thread (I couldn't find it with the forum search). The study was done in 2019. News link (one of numerous)...

If you do an image search for rocks or stones reflected in water, you often don't get exact duplications in the reflection - particularly when the objects are closer to the camera. Even the slight change of angle with regard to the original can change features because the aspect is different...

We are discussing the reflection hypothesis which implies that this is a hoax. It's ingrained and therefore detaches the discussion from the witness' claims. There are certainly other hypotheses that don't have to make that implication.

I hope you do not intend to imply that the clear water in a proud Scottish pond has any resemblance to such a mess !!! :cool: Seriously, in this case the particles in the water scatter the daylight. At the same time, they substantially weaken the contrast of the reflection. The details are...

That was precisely what I thought. Except that in my opinion, it's a box of sorts, not a rock. The plane puzzle is solvable - it may seem that the wrong side is up based on the specific configuration of the horizontal stabilizers...

If the fence posts were so far leaning apart in the reflection which is supposed to make them converge, then they'd be close to falling over. That weakens the rotation hypothesis. Anyway, my underlying point is still that there is no requirement and no indication for the photo to be rotated...

The photos from the location I've seen so far have most fence posts rather orderly and straight. And even if they were a bit crooked and outward-pointing, the reflection would counter that instead of amplifying it. So I'm not convinced that we can dismiss this point.

Didn't have a mirror at hand, so took a glass fram with a dark inlay. The reflected fence posts would converge like these hot glue cartridges. What we see in the Calvine photo looks more like the unreflected part here.

I know these are 'anecdotes', but if you search for water reflection photos, the reflection is almost always darker than the original.

The matchsticks in the reflection would not bend outwards. They would 'bend' (converge towards) inwards, to an imagined vantage point in the distance. OK, but let's turn this around (no pun intended) - what would require the photo to be rotated? Why would it have to be?

I don't think that's right. There is just one reflection from the object.

Because the reflection is usually not total (unless seen at a very low angle) so there is a loss of light.

However, that process would not agree with the perspective of the fence posts. Perspective would demant that they converge in their "up"direction. Instead, they converge toward their "down" direction. I still think that the reflection photo doesn't even require a rotation.

Stealing the images from the linked tweet - wouldn't you say this plane is upright and banking left?
