There's one (at least) spectacularly ugly photo of Alan Greenspan online. Maybe Oscar Wilde has the right idea in 'The Picture of Dorian Gray' - a lifetime of corruption leaves its mark.

I'm unsure if your Trinity video is accurate - it has assorted bits spliced together, and may not be in the original form. My collection of DVDs of films and newsreels has all those bits individually, including the billows of smoke in black and white negative, but I don't think in that sequence. However, I may be wrong.

the pilot smiling and waving does not look like he has the demeanor of someone about to embark on this mission,

There's a tiny bit of controversy over that waving. One source says he was telling the photographers to get away from the propellers. And also, it may have been on his return, and not his departure.

Who knows? It might not have even been taken on Tinian, or the night of the bombing.
