In 2013, Roscosmos decided to live broadcast the launch of the Proton-M, but the rocket beautifully exploded in the air and fell into the Kazakh steppe with full tanks of toxic fuel. Later, it was discovered that the reason was the upside-down installation of one sensor. An electrician and a controller were blamed, and Marat Nasibulin was charged with negligence.
So, I found out today that Vladimir Popovkin, the head of Roscosmos, who arrived at the crash site right after the incident, was heavily exposed to fuel components simply by being near the site (obviously, he wasn’t clearing the debris), and he died of cancer.
Interestingly, in 11 years, there has been no information on what happened to Marat Nasibulin, who was charged with negligence.
And RBC releases an article claiming that heptyl isn’t that toxic after all.
