28-year-old Captain Maxim Kuzminov seized control of a Russian armored combat Mi-8 helicopter and brought it safely to an airbase in the Kharkiv region in August of 2023.
According to a pro-Russian Spanish source cited in another Ukrainian article, he was shot 12 times and run over by a car before being found dead on February 13.
Edit: Clarified that the source is pro-Russian (as per the Ukrainian source and as evident).
We knew they have the means of killing people in Europe, so that shouldn't score Russia any points. On the other hand, the pilot being in Spain proves Ukraine must have granted him citizenship and allowed him to not be bound by any work obligations, just as promised.
