We can all agree -- THIS is a great aviation video...

Filming a movie is not necessary, it is optional. There may
even be alternative ways to film the scene. Those are
things that the FAA will consider before issuing a waiver.

It is possible that the scene was filmed in Mexico or some
other country, but that might make it legal, but it is still
unsafe.

Flying is not necessary either.

I do not agree that it is unsafe, except inasmuch as breathing causes
death. That's a very long lens on the camera; this compresses
perspective. Just like aerobatics demonstrations (which are
unnecessary), the visual tricks fool the viewer into thinking things are
a lot closer than they are.

Note the time delay is just a few seconds as the airplane
passes overhead and the wake rocks the boat, that was not a
telephoto lens but a real close pass.

And how do you know there was not some special effects contraption out
of sight behind the rowboat to generate those waves?
Remember... it's only a movie!

And it could all be CG from ILM starring real space aliens.
Your point is that you want to defend an unsafe operation
and I am suggesting that pilot's put legality and safety on
the top rung.

I watched the scene several times last night. Note that the camera
pans down to see the boat "rocked" but by what? The bow wave
doesn't look close to the boat and it seems hard to figure out
the distant between the plane and the boat. Doesn't a long lens
put the background out of focus? (or did I get that backwards?)

Yep. Everything is in focus with the long lens.

Nope. With a long lens, the depth of field is narrowed. That means
that if the foreground is in focus, the background will be =more= out of
focus than it would be had one used a short lens. There are of course
other variables (f-stop and film format) but all else equal, the long
lens narrows the depth of field and makes things seem "on top of each
other".

You can also get a sense of relative distance if you know the sizes of
the plane and boat in question, and measure the image.

Focus is a function of "depth of field" which is determined by the
apperature (f-stop) and shutter speed. The higher the f-stop (smaller
the apperature) the more the light rays which pass through the lense are
parallel, making the background more in focus.

Note the time delay is just a few seconds as the airplane

telephoto lens but a real close pass.

It was most definately a telephoto lens. I'm not convinced that the
wave that rocks the boat is the bow wave. We could figure all this out
- what kind of plane was it, what is its dimensions? (hull width, engine
spacing, wingspan). What is its typical approach speed?

It was also a close pass, but nowhere near as close as it looks. That's
how movies work. And remember, right at the end of a regular short
runway is stuff you don't want to hit too, but we take off of short
runways all the time.

It would be reckless for you and I and a few friends to go and do this.
However, Hollywood stunt people are well trained in these kinds of
things, they know, understand, and accept the risks (just like
aerobatics pilots do things that would be reckless for you or I to do
alone).

I have no problem with the flying in the shot.
