Maybe their argument is that France has nothing to fear from anyone, so why the secrecy? Of course it's nonsense no matter how you spin it. All militaries love secrecy (except maybe the ones that are just for show, but I expect even the Swiss Guard in the Vatican has its secrets).

I'm guessing their comment is from the view of the French being "cheese eating, surrender monkeys", a view not supported by France's long military history. This view was supported, for at least a few years, by a Google "I feel lucky" search for "French military victories" taking you to a Google search mockup site which suggested "Maybe you mean: French military surrenders".

Apart from the fact that the view of France as "surrender monkeys" is nonsense, it also makes no sense as an argument that their military wouldn't be interested in secrecy.

I live on a farm very close to this area. All the B-2s are based at nearby Whiteman Air Force Base. They fly over often -- one even fly over my farm today about an hour ago. This one was probably on final approach during the summer when the winds are usually out of the south and was probably about 2,000 feet above the ground.

Curious: ever hear any sonic booms?

I wonder if there are ways to get superior (compared to Bayer) color images from conventional raw-capable monochrome digital cameras (like Leica Q2 Monochrom) in static scenes using similar workflows of taking three separate shots.

It's standard when using reflectic/catadioptic objectives to peek back at where the satellites are: https://www.astroshop.eu/filter-wheels-filter-sliders/starli... This one has USB, the same style with manual operation via a teethed wheel is like 169 EUR at that shop. Or consider rigging a burnt-out DLP projector's filter wheel up, which comes with a motor and encoder that you could use to capture imagery with the fi…

Love both ideas…

Ugh, so when Google does a normal map update, unless there just happens to be a B-2 flying in the same spot, the conspiracy nutjobs are going to think there's some Google / US government conspiracy. The truth is the fact these planes exist and that there is a base nearby is public knowledge. Any country that cares already has its satellite imagery at much higher resoltion and realtime.

You can already see it happening in the first reply to this parent:

Is Google taking their own satellite pictures now, or are these from Maxar, or another provider?

This particular image was done by Maxar, you can see it in the lower right corner.

These are pushbroom linear sensors stacked up in the focal plane. The spectral channels are physically separated by larger distance than neighboring pixels in a Bayer grid. There is a time delay between each channel sweeping over the same location that gets corrected when the final imagery is aligned. The moving plane at altitude violates assumption of a static scene and exposes the scanning behavior.

I must say there is quite some beauty in the choice and structure of words here.

Funnily enough, I thought exactly the same when reading the parent post ! Grateful to be in such well-spoken company :)

I’d guess if you have fields in that area, seeing a B-2 over them is routine.

Now, seeing Tupolev over the fields in the area would give you chills.

Which particular Tupolev?

Apparently, until the USA recently withdrew from the Open Skies treaty, there was indeed a possibility of seeing a Tupolev in the area: https://en.wikipedia.org/wiki/Treaty_on_Open_Skies#Aircraft

You're absolutely correct, but as the aircraft is much closer to the ground than the imaging satellite I disregarded it. Spherical cows and all that :) I'm sure a military analyst would do the calculations!

It actually works out to be pretty close. A satellite flying ~17k mph at 250 miles altitude would largely have the same angular displacement from the ground as a plane moving 400 mph at 31,000 feet. Most satellites fly in an easterly direction, so the question would ultimately be what the inclination of the orbit is relative to the direction of flight.

Well no the speed of the satellite is irrelevant there, the background is not getting distorded at all
