pr00ne, that was XW417, a T5A which crashed on 9 Dec 1982.
The pilot was on a 'Co-pilot Enrichment Scheme' at 7 FTS. The course was designed to allow co-pilots to gain further first pilot experience in different scenarios to those that they had become used to, prior to moving on to different types.
The Court of Inquiry reached the conclusion that having aborted from low level due to low cloud obscuring the ground ahead, the pilot had lost control of the aircraft and was unable to regain control or eject before it crashed.
