Was that the one they used for recon?
Yes, that's the one. I used to know the identity of both MkIX's that shoot up the German car in Longest Day, but I can only remember MH434 being one of them. I'm sure the other is still flying though.
Now you've got me really confused.
I'm sure I've seen it in colour too. Maybe they originally filmed it in colour but decided to show it in B&W. I'm sure that would be easier to do than colour the whole thing afterwards.
It was filmed in B&W and the colour version is one of those that has been colourised. I've seen this done to a number of B&W films and I'm not convinced it makes them look any better.
