For completeness;
The aircraft is S/N 258112 and at the time was registered as OK-1
After repair it was sold to Brazil but has since been sold to a company in Nevada and registered N812GJ.
According to my book "Hawker:The Story of the 125" the incident took place on the 8th August 1988.
I've heard two slightly different versions of what happened in the Cockpit, and who was flying, but have no idea which is correct!
