I had wondered myself how they got those pictures.

The interesting thing is that the camera which was made to do that
is a Hugh monster - uses a spinning mirror and dozens of cameras to
capture the images. It went surplus, and was bought by a lightening
researcher/hunter. He replaced the film cameras with digital ones,
and mounted it in a trailer. However, it is sort of "point and shoot"
as in "point the side of the trailer in a direction, start the camera,
and hope something is there when you 'shoot'". Because it is still
ten minutes to spin up the mirror, and then twenty minutes to download
all the images to prepare for the next shot.
But he's doing some rework - hoping to put a periscope on it,
which can be swiveled and aimed. And seeing about faster downloads
from the cameras to storage.
This was written up in a "recent" National Geographic, which I
read at the library.
