Falcon Heavy Test Flight猎鹰重型火箭测试发射与多级回收

SpaceX's livestream of the Falcon Heavy test flight, including the launch, side booster landings and Tesla Roadster payload. It was the first launch of the most powerful operational rocket at the time.

Why HN likes it: HN commenters cite it as a landmark launch broadcast, and also dissect details like the duplicated booster landing feeds.

“You should watch the launch, its probably one of the most interesting engineering projects of the last few years.”
