A pair of recovery ships was stationed in the Atlantic well before splashdown and quickly moved in, lifting the capsule from the water within an hour.
In 2014, NASA awarded contracts to SpaceX and Boeing to develop spacecraft to launch US astronauts.
This final phase of the Demo-1 mission was perhaps the biggest test of Crew Dragon's new build.
It's returned to Earth after a successful uncrewed trip to the International Space Station.
Canadian space station astronaut David Saint-Jacques was the first to enter the Dragon capsule and the last to leave this week.
The last generation of United States spacecraft, the Space shuttles, landed like airplanes. Six hours later, the capsule carrying a test dummy parachuted into the ocean, a couple hundred miles off the Florida coast. Crew Dragon splashed down at approximately 8:45 AM EST.

We have splashdown! The Crew Dragon undocked from the space station at 2:32am EST this morning and started the journey back to Earth. Boeing is set to test their crewed vehicle in Spring this year. SpaceX is shooting for summer. But that tower had to be jettisoned before the spacecraft reached orbit - before the spacecraft even separated from the rocket, in fact - briefly leaving the crew with no escape system at all if something went wrong.
If all goes as planned - as was the case with the first half of the mission - SpaceX could conduct a crewed test flight as early as April.
SpaceX and Boeing, which is building a vehicle called Starliner, have contracts worth up to $2.6 billion and $4.2 billion, respectively. Historic aerospace company Boeing are also readying to fly to the ISS with their own capsule, dubbed "Starliner", in the coming months.
The space station's three-member crew greeted the capsule last Sunday, with USA astronaut Anne McClain and Canadian astronaut David Saint-Jacques entering Crew Dragon's cabin to carry out air quality tests and inspections.
"However, NASA and SpaceX still have work to do to validate the spacecraft's performance and prepare it to fly astronauts". "That [shape] could potentially cause a roll instability on reentry", Musk said. But he said he thought it was "unlikely" since the company had run "simulations a thousand times".
"You actually see the light from the atmosphere, as it heats up the external portions of the space craft".
Elon Musk, the CEO of USA private aerospace manufacturer SpaceX, called Russia's rocket engineering "excellent" and said the country's rocket engines are the best now flying, also suggesting that the reusable version of Russia's Angara rocket would be "great". NASA has to pay, of course, and the actual launch of each new group of crew members is largely out of their control.

The Stamford Bridge boss went on to say he is much more content after his side clung on for a 2-1 win over Fulham on Sunday. His reaction today was really very good. "He understood the mistake so he was able to react very well", Sarri said.
