A YouTuber got into a SpaceX launch site and filmed himself with the prototype SN11 Starship, days before the rocket exploded in a test flight

• A YouTuber entered a SpaceX facility and filmed close-up videos of the Starship rocket, SN11.
• Caesar posted an apology video, saying, "It was illegal, but ... I didn't really think about that."
• He recorded the Starship SN11 days before it exploded during a test flight.

A YouTuber filmed himself entering a SpaceX facility in South Texas last week, where he managed to get close to the company's prototype Starship rocket without security stopping him.

The YouTuber, known as Caesar on his channel Loco VlogS, entered the Boca Chica grounds of Elon Musk's company in late March, The Verge first reported Thursday. He has since deleted the video, which The Verge reported had five likes and 100 dislikes.

Another YouTube account reuploaded the recording on March 31. It shows Caesar walking around the 16-story-tall prototype Starship SN11, walking underneath it, and getting close to the three truck-size Raptor engines. No one else appears in the video. Caesar does not touch the rocket, which is on stilts.

Caesar filmed the Starship rocket days before it exploded on landing during a test - the fourth time a Starship prototype crashed during testing. Musk eventually wants to build 1,000 Starships to carry people and cargo to Mars, where they can establish a human settlement.

Caesar didn't immediately respond to Insider's request for comment, but he posted an apology video on April 1. "Yes, it was wrong. Yes, it was illegal. But in my eyes, in that time of moment, I didn't really think about that," he said.

"What went through my mind was, 'Okay, I'm never gonna get this opportunity again.' So I went for it. And, well, this happened."

SpaceX didn't immediately respond to Insider's request for comment, but a NASA spokesperson told The Verge that "SpaceX notified NASA that they investigated this incident."

The agency "takes safety and security very seriously," it added.

This isn't the first time that fans have entered SpaceX premises. Insider reported in 2019 that a SpaceX fan was accused of criminal trespassing and arrested on suspicion of getting too close to a rocket prototype called Starhopper.
