A question I have is, were the prop bolts safety wired?

Doesn't matter...I had this happen to me once...same outcome,
un-eventful landing on the runway.

With a wood prop, when cold, dry, winter sets in, the wood
shrinks away from the previous torque settings allowing the
bolts to fail in just a few minutes. All of the safety wire
in the world doesn't help.
