Those pics are awesome I just can't figure out why some people had their
backs to the jet on its flyby how could you not be looking at it zooom
by your nose???

Telephoto lens magic. Those houses in the back ground are miles away
from the camera. It just happened to be a real clear day.
Note the scale on the lower left of the map.

I don't think so . . .the "head scale" doesn't look right, comparing the
guys on the boat with the helmet on the pilot.  Also, note the big space
between that boat in the foreground and the ones behind it.  That looks
like the cleared channel.

My guess is that the guys on the boat were watching the "bait" while the
"skunk" was sneaking up behind them at several hundred knots.

So you don't think the lens was telephoto or you don't think the houses
were miles away? :)

The boat looks like a Coast Gard boat. If so the job of the crew was to keep the boat traffic out of the path of the jet. Perhaps the Coast Gard boat
was also a marker for the pilot.

I don't think that's the explanation for the way the guys on the boat
were facing.  Even Coasties watch airplanes, and would be watching this
one if they knew that it was there.

Airshow pilots don't use boats for markers, they use terrain and
buildings -- things that don't move, not even a couple of feet one way
or the other, like an anchored boat (and this one isn't anchored, look
at the wake).  A 1-degree error in the run-in leads to loud and
expensive noises.  They are looking way past anything that they would
fly past or over, usually using line-up markers which are several miles
apart, and several miles past Show Center.  Just like in formation
flying, you line up two features and keep them lined up, and trust
everyone else to be keeping THEIR two things lined up.

You did not answer the question :)


FAA 91.119 Minimum safe altitudes; general

(c) Over other than congested areas.
An altitude of 500 feet above the surface except over open water or sparsely
populated areas. In that case, the aircraft may not be operated closer than
500 feet <<< to any person, vessel, vehicle, or structure.

500 feet is 1.6 times the length of a football field. At near transonic
speeds you won't hear the aircraft until after it passes when it is
only 20 feet above the water.

"Supporting Evidence: Witnesses, Police, Photographs."

"If you took photographs, we need to know the >>> lens used, <<< and the height
of any identifiable landmarks that appear."
