What's to say? It was determined that the leader's (Maj. Norm Lowry)
aircraft sustained a mechanical malfunction that caused it to crash
(failure to pull up after completing a loop),...
I seem to recall that there might have been a loose bolt in Major
Lowry's stick that had caused the stick to jam at just the wrong time.

I believe the Board put the blame on a "bob-weight" that effected the
feel of the stick forces...no jamming that I recall. I was an
additional duty safety guy in my squadron, and briefed it. The T-38
FAIPs in the sqdn were skeptical (to put it mildly) of the "official"
explanation.

ISTR that the Accident Board also found that the Formation was lower
than briefed/expected at the apex of the "over the top" maneuver being
flown, and the findings speculated they could have pulled out if...

Sad day none the less.
