We were on 134.12 when this happened - he was using the c/s "Allred 5" and said he'd had a "total instrument failure", and then a "trim failure" (3 POB I think).
Excellent job as ever by London ATCC, the aircraft was last heard being pointed at Exeter, I think the crew said they were familiar with there, and the wx everywhere else was fairly poor.
Any info on who "Allred" are (and just want to know if they made it safely onto terra firma)???
