I thought the last Valiant sortie was on. Dec 9th, after we were recalled from a hilohi in 865 of 207 sqn.
There is the possibility that my log book has the wrong date and it was the 9th.
What I remember was that as we crossed the threshold there were the lights of the Station Commander's car stopped in front of a Valiant that was approaching the holding point. We heard that he had driven in front of it because he could not contact Air Traffic to stop it taking off when he was told that they were grounded.
About 30 minutes after we landed a bomber landed and that was that.
It was in the dark at about 19.00hrs so does that tie up with your memories.
