Earlier quoted context omitted.

My napkin calculations are that the three channels are ~10ms apart, given the bomber is 69 feet nose-to-tail* and an assumption of 400 mph velocity. * http://www.dept.aoe.vt.edu/~mason/Mason_f/B2Spr09.pdf

I would assume that the plane or satellite moving affects this too, it's presumably being corrected but there might be some parallax.

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!

Interesting how you can see the chromatic aberration on the bomber but not the ground. I guess that this implies that the optical and/or software correction that they're doing only works within a _very_ narrow focal plane, given the relative proximity of the bomber to the ground. This is kind of surprising, because if the tolerances for avoiding chromatic aberration are that small, whatever is collecting this data wo…

I wonder how low it is, found the shadow of it close by 39.02468482732915, -93.6023120071418 https://www.google.com/maps/place/39%C2%B001'28.9%22N+93%C2%...

nice catch! I think the altitude could be calculated roughly if we knew the the day of the year the photo was taken.

Interesting how the three separate R/G/B images are taken independently a few ~seconds~ milliseconds apart, with a different color filter placed over the image sensor. I assume this is to maximize resolution, since no Bayer interpolation [0] is needed to demosaic the output of a traditional image sensor that integrates the color filters onto the sensor pixels themselves. As these satellites are not intended to photog…

Can you calculate the time of day from the shadow's length as well?

Shadow of this object is also distorted: https://goo.gl/maps/VWwtt1PbLJVkbiBS9
