The Transportation Safety Board (Canada) has released a report on the
fatal mishap at the Saskatchewan Air Show in 2005. Two members of
The Masters of Disaster demonstration team died in a midair collision.

Their findings:

1. The Dairy Turn manoeuvre had been modified such that a temporary
loss of visual contact could occur immediately before the aircraft
crossed flight paths. This modification made timing critical and added
two potential points of collision.

2. The manoeuvres immediately before the collision indicated that the
performers had not established a clearly understood contract for the
revised manoeuvre. The actions of each performer negated the actions
of the other, and neither pilot took positive action to regain visual
contact.

3. The timing of the manoeuvre was lost when the Waco turned late at
show centre.
