Re: Mesmerising
Being closer towards the "old fart" end of the Reg readership than some, I thought I should share a link to a 1977 book ("Worlds within Worlds - A Journey into the unknown") that I recall fondly from my childhood.
This includes several shots similar to the second video - including one of the bomb tower just after the fireball has started at detonation. The tower is still there, and it has not yet been vapourised - incredible.
There are lots of other high-speed or specialised (e.g. Kirlian) images in there too.
