What kind of player does this video use? It doesn't play in my IE and
there is no link on the page to download the player.


You probably have your security set too high, and disallow the necessary
Control.

Look again, front seat passenger (adult), back seat passenger (adult male)
and I'm guessing that a litter with a medical patient behind the pilot,
look at the oxygen support and other medical supplies.

Is that the same (crash) plane or a second plane?

When I saw the post-crash fire and smoke, and the people on the ground being
treated, I figured the crash plane was toast.

Looks to me like the flap setting may be "a little" more than usually used for
this type of takeoff, but not enough to be causal or contributing.

Hard to say much about speed from this type of video, but he looks slow.

Could be a problem with the C/S prop. The 182, with the prop at fine pitch
usually has abundant excess horsepower on takeoff. If he set the prop wrong, or
if it malfunctioned it could look like this.

Otherwise, as others have stated here, you'd have to know something about the
density altitude at the time, and the loading of the aircraft, as well as
whether the engine itself failed to develmop power.

place, as you don't see the ailerons moving.

Unlikely. The standard Cessna gust lock locks the elevators in an almost
full nose-down position - it's improbable he'd have been able to raise
the nose at all. It just looks like a classic insufficient
airspeed/mush/stall accident.

True. It sure looks like a classic mush/stall though. He got airborne
too early, but with plenty of potential ground-effect acceleration space/time.
Between the partial stall with resulting wing drop, and perhaps seeing the people
ducking for cover, he tried to suck it up and over. Without ground effect to
accelerate, he got irrecoverably behind the power curve.

CG problem..probably aft...which would
make rudder potentially worthless.

Why? An aft CG will reduce the rudder's arm and increase the p-factor,
but it won't render it useless.

It's the same plane. The footage is in chronological order.

Don't see how he could have done that. Have you *ever* tried to take off with
the throttle(s) / prop(s) / mixture(s) not pushed full forward? Particularly on
a maximum effort takeoff? (Maybe holding back a little bit on a turbocharged
engine with the throttle as redline dictates).

What was the distraught FRONT seat passenger saying - through her tears? She
did not appear happy.

Was she an injured passenger, too - before the crash?

I don't know Spanish, so I can't tell. Perhaps she's crying because her son
is ill, or because she's afraid of small planes.

No injury is apparent. (According to the accompanying text, the passengers
all died in the crash, and the pilot was critically burned.)
