And a big hole it made too....Dumbo jet
....I helped pick this one up (well the pieces). Due to the nature of some of my duties at LBH at the time had a high clearance, had to sit in a tent after our shift and go through all the pieces of pcb and declare those of "interest" to the rafp who then bagged and sealed them!! Don't think we ever found the fin which was of great concern at the time.
More about EMI yes but not for here as has been stated, in fact my memory has gone blank too...................................
