I'm having great difficulty locating either the AAIB or NTSB official reports. I'll certainly attempt to chase up the AAIB report because I want to get it straight in my own mind, what really happened.
the AAIB report which I am scanning at this instance is :
AAR No. 4/89 (EW/C1059)
The NTSB received a copy of the report, but to my knowledge did not produce a report of their own.
