It did not get by me.  I had it right when I first saw it.  They should hire me.

coppercone2:
Do you know if special conditions make this happen? How does it not happen every single time you are approaching to land or see something at the wrong distance in the air before the camera focuses?

Is it not always displaying triangles?

If you want aperture, consider gravitational lensing -- using a star's gravity to focus the signal from a long way off onto a receiving (or transmitting) antenna located on the focal line.  I used to hang out with Frank Drake, and that was his dream receiving system.

For what it's worth, I do *not* believe that aliens are buzzing the earth in their UFOs.  They're out there, just not *here*.

It doesn't display the aperture when properly focused.  It should also not happen when the aperture is small enough to increase the depth of field to cover the source.  When I used my infrared monocular with the daytime cover which is just a pinhole lens, then the focus does nothing.

I figured a plane will routinely come across unfocused things in day to day operations.
