The prop spinning under power causes a rotation of the airplane to roll. That is torque. Compensated for by aileron control.
It also causes the airplane to yaw, called "p factor", causing the axis of the plane to move nose left with most airplanes. This is corrected by right
rudder input. It is best to set the trim tabs on the aileron and rudder to take care of this before taking off. The bigger the engine and prop the
more this comes into play.

You don't get lift and airborne without "that spin" 
Don't believe everything you think....

 ATTENTION PILOTS:
No 'DK' post or reply reading while in takeoff or landing modes... Please wait until you are in Cruise mode or on the ground, stationary!!!

Pilot is a low hour novice. It's always pilot error.

Oh come on, you don't know that.
It's Baja. Maybe he dropped his beer.

Absolutely correct. He could have dropped anything including a roach. NTSB would find the accident could have been avoided.
Probably doesn't know what left drift is. Rank amateur.

I heard he is 70, should have a few hours. Unless he just got his license it must be something else. S&H may have something there.

Unfortunately, age doesn't mean a thing. He could be a pilot for 40 years and still be low hours.
The video shows he drifted a long ways before hitting the fence. He had ample opportunity to self correct. Doesn't mean he's a bad person.
Just an incompetent pilot.

He probably had a "senior moment" and froze up, with a momentary lapse of reasoning ability.

Pilot's Handbook of Aeronautical Knowledge, Chapter 16:
''POOR JUDGMENT CHAIN is a series of mistakes that may lead to an accident or incident. Two basic principles generally associated with the creation of
a poor judgment chain are: (1) One bad decision often leads to another; and (2) as a string of bad decisions grows, it reduces the number of
subsequent alternatives for continued safe flight. ADM is intended to break the poor judgment chain before it can cause an accident or incident.''
''AERONAUTICAL DECISION MAKING (ADM) is a systematic approach to the mental process used by pilots to consistently determine the best course of action
in response to a given set of circumstances.''

I have been teaching extreme stuff for a very long time.
The older we get, the less we are sometimes able to adjust in situations of high stress. Especially unfamiliar stress.
Signs of that inability to react start in the mid 50's (my limited observations)
70's? High likelihood.
However, mental training and lotsa practice eliminate those lapses.
Remember those old guys making a wrong turn into a farmers market, plowing through the crowd unable to stop?

Odd. My mind has a tough time ascribing this to outright failure to maintain directional control - that's not a narrow runway and that's a LOT of
drift. As already covered in this thread, there is a slight left-turning tendency on takeoff but it's something you learn to correct for on your
first few takeoffs as a student pilot. I guess the guy could've frozen up in the heat of the moment and figured he'd just yank it off the ground
before he hit the trees?
On the mechanical issue side, something like a seized left main caliper, or nose gear steering link failure, perhaps?
Do Mooneys of that era have steerable or free-castering nosegear?

I live near the runway and went down to look things over. The damage I can see is all from the crash though, of course, a serious investigation might
uncover some malfunction. What does bother me is that the main gear seems to be retracted and the nose gear is down about 1/4 and the prop tips are
bent. I cannot imagine pulling the gear up at an altitude of a few feet. All of that could be crash damage though.
Second hand word around here is that the pilot complained of a wind gust. If someone held a gun to my head and forced me to make some half baked
judgement, I would say that it was pilot error triggered by unfamiliarity with the field. Pulled it off the ground too soon and drifted into the
fence. I don't believe the field has a history of accidents.
All total speculation on my part, of course. It's a parts plane now. Everything is either bent or tweaked or broken.

Dolly Vincenza was the person there who caught this on video - actually they were two different videos - and sent them to me on facebook. I combined
the videos into one and did some minor editing before uploading it on our group.
I see somebody has already hijacked it and uploaded it to youtube...

I watched the video several times
at 0:14 a separate cloud of dust puffs up behind the plane
right at that moment it starts veering left
before the puff of dust the plane was going straight

Did Dolly have more info? Be good to know if there was a mechanical problem.

Here is what was shared in our group:
The plane, a Mooney M20C was registered out of Meza, Arizona to Arthur Goold (N6246U) and he had made the trip down to Mulege to help with the
transport of some doctors working with the Flying Samaritans. According to the pilot he was hit with an unexpected strong gust of wind when about to
take off from the Serenidad airstrip, bringing the 4 seater aircraft back down hard and pushing him to the left along a fence near the airstrip,
shortly after 9:00AM local time.
Paramedics from the Red Cross as well as a local military patrol responded to the incident, offering to take the men to the local hospital. Both men
refused, only needing minor first-aid attention from the emergency responders onsite.
Fortunately, both men were able to walk away from the crash with the plane suffering the majority of the damage to its rotor and right wing.

Maybe that "puff" was just the pilot exhaling....
