I think Howard Hughes and Chuck are closer to the mark.

This has all the hallmarks of a classic "Black Hole Departure" .

Take off was at night, in an area devoid of ground lighting, with possible showers.

Somatogravic illusions can create a sensation of over rotating, causing a pilot to relax back pressure.

An empty C310, Baron, Chieftain or Shrike can accellerate quite rapidly, this is the intro to the somatogravic illusion,
with the vestibular senses reacting to the accelleration.

The typical Black Hole departure accident scenario is usually a gentle descent with a tendancy to veer slightly left.

Impact is typically around 1.4 km from rotation.

Recent examples are the Chieftain at Bathurst, and a while back, the C90 at Wondai, Qld.

Training can make the pilot aware of the somatogravic effect, and the defense is attitude flying.

After lift off the aircraft is set up for 8 degrees nose up while in the take off configuration and,
after gear / flap retraction, an attitude of 12 degrees nose up should be established.

These simple attitudes guarantee Blue Line (Vyse).

Performance is monitored against the VSI and altimeter, and slight attitude corrections ensure the desired airspeed.

Very few GA training outfits teach attitude flying, this can be verified by watching twins taking off and held in a level attitude to attain blue line.

Lester Neideck, Sunshine Coast Air Charter was probably one of the last to teach attitude flying.

When pilots finally get to airlines, that is usually their first intro to setting attitude flying.
