I wondered if it might have been.

That Dakota suffered a classic case of rotating too soon and too steep causing a stall. (Aerodynamic, not engine)
The left wing had the higher angle of attack and stalled first causing it to bank hard left, striking the ground.
Cause could be either mechanical control lock or over zealous pilot technique.
Contol lock is very possible as the tail wheel wasn't off the ground but a few seconds before the aircraft rotated, jamming the tail wheel back against the ground like the pilot couldnt control it.
No way any pilot would intentionally rotate that aggressively especially on a classic, heavy aircraft.
As mentioned it does appear the flaps were not selected for takeoff, but this should have just caused a longer than normal takeoff roll if the pilot was doing his part, not the sharp rotation seen.
Extremely glad everyone survived.

As far as the junker is concerned, aircrafts dive do to lack of lift, not engine power.
An aircraft turning 180 degress then plummeting could be due to a single engine malfunction and loss of airspeed. The lack of airspeed reduces the effects of the ailerons to the point where full inputs are counter acted by the running engine (called vmca roll, or single engine minimum airspeed control).
If the running engines power is not reduced and the aircrafts pitch attitude reduced to regain airspeed, the running engine will eventually roll the aircraft over and into a dive.
At high altitude, this could happen at a much higher airspeed than whats published in the SOP as published airspeeds are tested at lower altitudes where aircrafts perform better.
