The second pilot of the turbine Lancair that went in on the Bellarine Peninsula was an acquaintance of mine and a very good friend to my partner. He was helping the owner sort out the highly modified Lancair. According to the ATSB report, they deliberately stalled the aircraft three times and didn't come out of the last one because it developed into an unrecoverable spin (I think).
The ATSB report concluded that if you play with an experimental aircraft, you are your own test pilot and if you do not plan for the unexpected then you face the consequences. Rob is very, very sorely missed.
