Battle of Hastings, 1066

Last time that the island of Britain was successfully invaded. I think the culture of chivalry that the Normans brought was what changed English culture to become what it is today and away from their Anglo-Saxon routes. I would even go as far as to say that the Normans were proto-imperialists and the culture they helped develop in England, France, and the Mediterranean led to a big chunk of the old imperialism of the 1500-1700s (minus the Spanish/Portuguese/Dutch).

Sure as fuck not the fuck-ton of them that have gone on in the last 8 years.

Hiroshima.

Sorry, had to make the dark joke.

The serious answer is the first Apollo launch. Because space. That’s when real space ventures became a reality rather than a dream.

Tbh though, if it was some kind of magical thing where it was possible, the moon landing would be a bigger deal for me. But there’s no way without going into fantasy for that to happen, and it wouldn’t be the same because part of the cool part of this idea is being there, in person, with the ability to experience the entirety of the event. Can’t cram another person into the lander at all, and that’s where I would want to be. But I’d be perfectly happy to be in the crowd watching a launch

The astroid impact that wiped out the dinosaurs. Would be cool to see a world ending event as the sky lights on fire, oceans evaporate, and a super tsunami.

Normandy beach, d day.

It’s be fun to look around for a few seconds then get shot
