I think you're being a bit harsh there, Vern me old.
A lot of viewers have short memories and won't know who JN is - so the intro. was pitched correctly, in my view. Also, the programme was aimed at the genpub rather than at experts, so the presentation manner was entirely appropriate. The V3 tunnels were astounding and the interviews with German survivors added an extra, very welcome dimension.
Yes, there were some continuity errors (I'm pretty sure that 617 never flew the Lancaster B II, for example), but overall a cracking programme well presented.
Now, could we have something on the Lincoln / Canberra / Vulcan / Tornado era and a look ahead to the F-35B please, John?
