I can remember de-briefing the AEO, the Job Card read "Simultaneous Loss of signals from both Fwd and Aft RWR aerials".
The fin cap, IIRC was recovered a few miles down the extended centreline, the screws which held it on had worn through the fibreglass of the fin cap. This was not unusual, we just placed very large cup-washers (from the Jaguar) under the screws, and it prevented further wear.
