It sounds ridiculous that an explosive tube taller than a building could fling a satellite into space, fall back to Earth, and stick a landing on a wobbly ship at sea.
But seeing is believing.
The footage takes you to the deck of SpaceX's comically named droneship, Of Course I Still Love You.
This and other ships are designed to catch first-stage rocket boosters: the largest and most expensive piece of the company's 229-foot-tall (69.8-metre-tall), US$62 million Falcon 9 rocket system.
Cameras stationed all over the ship's deck recorded the latest booster landing on March 30, 2017 - it was arguably one of the most important moments in SpaceX's history.
"It's been 15 years to get to this point," Musk said during a live broadcast of the launch.
"I'm at a loss for words."
SpaceX edited three video feeds together to make a supercut of the booster landing, and it's best to watch with the sound on:
To get a sense of scale, the image below shows a fully stacked Falcon 9 rocket being hauled out to a launchpad. (Take note of the size of the people at the bottom right.)
Orbital rockets like these are complex, multi-million-dollar machines that send our most precious satellites, supplies, and people into space.
Yet since the dawn of the Space Age, all the boosters we've used have turned into garbage right after their engines were ignited.
That paradigm shifted in a major way on March 30, when SpaceX achieved the first-ever full reuse of a Falcon 9 boosters.
"This is going to be a huge revolution for spaceflight," Musk said.
He later told reporters that SpaceX will soon try to launch, land, and re-launch rockets in a 24-hour time frame - an aggressive goal that Musk said would make it "possible to achieve a hundredfold reduction" in the cost of getting stuff into space.
"This is potentially revolutionary," John Logsdon, a space policy expert and historian at George Washington University's Space Policy Institute, previously told Business Insider.
"Reusability has been the Holy Grail in access to space for a long, long time."
Musk's company is also due to debut its similarly reusable but more powerful Falcon Heavy launch system this summer.
