Last night I watched Channel 4’s documentary about recreating Barnes Wallis’ bouncing bomb from the second world war. Apparently most of the documentation and research into the project had been lost in a flood in the sixties, so a Cambridge professor recreated the entire project.

However, the entire thing was let down by the first two minutes – it was based on the question “Will they manage to recreate the bomb?” – which unfortunately had been answered in the first two minutes when they showed footage of the new bomb skipping across the water and hitting the purpose-made dam.  Indeed, I think they’d even shown that footage in the trailers for the damn programme.

I don’t know why they did it this way – the documentary was still interesting in all the technical challenges and so on that went into the initial project – but it would’ve been more interesting if you didn’t know the answer before the research even started.
