Correction *falling at a rate of about 1000'/min...

What I find interesting are the comments made on such things at
trajectory of the object. As the camera is falling, it is not falling
vertically. It is falling at a rate of about 1000 ft per second and
gliding too. Because the camera was mounted on the helmet, it's view
is whatever way the guy was facing.
So, if you take an object, like a baseball and hang it from a string
30 feet in the air and then step back 40' and take a picture of it
while standing on a 10 foot ladder, it's going to look small.
Then if you take the ladder move it 10 feet closer to the ball and
lower the ball from 30 feet to 25 feet and then climb the ladder but
take the picture at 3/4 the height of the first picture, you will see
the ball is bigger and the angle will be different making it look like
it is moving on some arc or curve (in a composite of the two
pictures), when all it did was drop vertically. You keep doing that
and pretty soon you and the ball will meet and the ball will look
bigger than it actually is. So the ball, with a perfectly vertical
decent, will not appear to have a vertical decent. One can actually
just draw this out with a pencil and paper without the need for a camera!
