Videos of this aircraft are somewhat elusive.
There's a recent upload of the last flight of the Britannia taken back in 1997 here.
Some rather impressive low passes in it. Unfortunately, as always, there's some noisy asshat who has great difficulty keeping his mouth shut. Fortunately he doesn't talk over the best bits, but its close.
I think I've got most of the Britannia releases in 1:400 and while both manufacturers are good, I think the GJ/JC one is just a little bit better. (Doesn't stop me from getting all the AC ones though.)
The GJ/JC 100 series is superb. I'm amazed at how it isn't
an obligate tail sitter.
My dream scenario, to continue the allusions in the above posts:
We've got company... Britannias!
Uh... All of 'em I think.
