Sarah, Looks like you've had a win with SRAM!
If you're interested in the details of what happened to your Dad's aircraft the No 2 engine was the cause. The main shaft broke up and a turbine disc went through the bomb bay - severing the control runs. Approximate point of failure shown below. No doubt the BoI papers will fill you in.
Your Dad's 'desk' was number 132.
