Wow!  How in the hell do you get a shutter speed fast enough to stop
the *props* almost dead?!  I assume since they're quite large they spin
slower than "normal" sized props, but still...

Nice shootin'!

Those photographs were shot handheld through a 400mm lens. I would
guess the exposure time was 1/800th of a second. It had to exceed
1/400th of a second, else the camera would have warned me the speed was
too slow to be handheld. Aperture was f5.6.

My guess is faster than 1/800.  Here is a link to a picture of the same
aircraft type I took at Kirtland at 1/500 second exposure time.  Admittedly
the phase of flight is different, but I'd be surprised if the prop rpm
differs so greatly.  In mine at 1/500, the prop blur is quite substantial.

If the news reader wraps or otherwise makes the above link not work, here
is a tiny URL to the same exact place.

I do see the difference.

I wasn't paying attention to the shutter speed. I had the camera in
aperture priority and wide open at f5.6. It has been my experiance that
with ISO 100 film the shutter speed doesn't get higher than maybe
1/1200th or so.

nice catch, Miso.

But with regard to the CV-22 and UAV's,...
Is there an implication that UAVs are perhaps being test-dropped from CV-22's ?
No need for a landing field for take-off in that case, say somewhere in a very
mountainous country where goats can be your best friend perhaps?

Hmmm,...
