We have to be fair here, he probably only had seventy hours of training for his license.  :)

I don't know Chuck.
full up elevator..Nosewheel at least a foot off the ground.
Aircraft hauled off with what looks like about half the runway left..
keeping the nose high..

I would think more than 70 hours to learn that technique...

I think I have seen this clip before and  the old grey stuff has a memory that it was an example of high altitude and a hot day and possibly aircraft recovery from a field with trees and he just had no performance and lost it.

I'm only a humble 3 bar but I know that might have gone a lot bette had he used 20 degrees of flaps instead of the ten that appears to be selected.

It appears he was at critical alpha right from the start and exceeded it just after lift off.

That is the impression I got as well.
I have seen more than a few new CPLs that were taught that way.  For some reason they think that on a short field you should not use as much runway as you can and try to get the plane airborne at the earliest moment possible.
And then the excessive nose up technique..
A few CFIs need to be looking at how their instructors are teaching short field take offs.

Tough takeoff. Can see the nose drop, AOA reduce and plane stabilize for a moment just before it rises again and wing drop. Maybe those trees were looking too big and he pulled up. Wonder if too hot high and heavy. 20 degrees might have been better though if that's a 172 POH says 10

Looking at that video I just see someone who is scared and it's hard to tear apart someone in that situation.  From the step over the one wheel I wonder if this 182 was a jump plane with a fairly green commercial pilot flying it, possibly off on his own for the first time.


He was cautious but wrong, this video would make a good case study in a commercial-level obstacle takeoff PGI.
