After Dispersing The Boats
After a while, the SpaceX staff dispersed all the onlookers and reached the capsule. As they extracted the astronauts from their capsule, the boats continued to hover very close by. It was too close for comfort as the onlookers wanted a better view of this process. They had no idea that they were unwittingly putting themselves at risk by doing this.
What Made It So Dangerous
There were toxic fumes around the capsule that had just returned. They might kill a person or cause anyone nearby to self-ignite! This surprising turn of events could have led to disaster for the astronauts, the recovery team, and the people on the pleasure boats. Where did these gases even come from? You see, the toxic substance in question serves as a propellant for the capsule while it makes its way back down into the orbit of the planet. Nitrogen tetroxide, occasionally nitrogen peroxide, is brown in color. This is a type of hypergolic fuel, which means that it can self-ignite. We would rather not be around that!
