I find it a bit disconcerting that the briefing for the descent/approach was not more `formalised` ,ie everyone on the same `Hymn-Sheet`, front and rear crew ,copies of the `route` and noting all the heights..nothing seemed to be mentioned.Consider also that the W/Op had been on the crew of R116 doing a similar sortie on 8 March just a few days earlier,and had `that big rock` pointed out by that crew`s W/Man,when it had been overflown on the departure from BLKSD at 900FT,as that crew initially decided on a flyover at 500ft,but then decided 900ft would be better.
I would have thought that on return there would have been crew-room chat/discussions about a sortie into an unfamiliar `patch`,and the procedures.
