On January 16, during a test flight of the Starship spacecraft, its upper stage had to be detonated. The debris fell on several islands in the Atlantic Ocean. The U.S. Federal Aviation Administration is now investigating the causes and consequences of the explosion.

Consequences of the Starship explosion
On January 16, SpaceX was conducting another test launch of its Starship super-heavy space system. It is two-stage, and fully reusable. During the launch, the lower stage was successfully caught by a giant mechanical arm. But the second, namely the spacecraft itself, had to be exploded for unexplained reasons.
The exploded spacecraft decorated the sky with a spectacular avalanche of fiery debris and some of it reached the surface of the Earth. Now the U.S. Federal Aviation Administration is forcing SpaceX to investigate the incident with their spacecraft. However, this is not something that Elon Musk’s company is very eager to do, as they haven’t even told the reason for exploding it yet.
Most of the debris fell on the Turks and Caicos Islands. The Internet is already full of videos of people showing strange fragments. And at least some of them, like the hexagonal heat shield tiles, are definitely from Starship. Fortunately there were no casualties from their fall and property damage was minimal.
Question for SpaceX
To establish definitively all the consequences of the fall is one of the tasks of a future investigation. However, there is a much more interesting question for SpaceX: why did the debris fall on Turks and Caicos at all? Danger zones are clearly calculated in advance, and everyone seemed to know where the fall would be in case.
However, when Starship exploded, the pilots of the planes had to change course and choose other airports, even though they were in areas that seemed to be considered safe. So the spacecraft did veer off course.
And SpaceX has a good reason to claim why this is the case. Somehow after 8.5 minutes of flight, telemetry stopped coming from the spacecraft and there was a fire, so the real causes may indeed be searched for some time.
