In contrast to US & ESA programs, Russians do not employ true RSO destruct system. If rocket loses control, ground officers can send manual shut down command but they never destroy rocket in air to reduce risks on people and assets. Instead they let that fully loaded rocket impact the ground.
Why Russian doctrine in this case differs from US & ESA? Is this a form of carelessness or there is another explanation besides launching rockets in an uninhabited areas?
Kourou launch site is also in remote and unpopulated area but ESA still employs RSO destruction.
From many videos which could be found on internet, Proton M rocket failure in July 2th 2013 caused huge explosion similar to small nuclear bomb and it's shock wave caused shattering of windows in nearest town. Impact of rocket caused rapid, confined and efficient mixing of hypergolic fuels and therefore strong detonation. I think, that if rocket was destroyed in air on time, it would cause very fast burning - fireball, but not detonation. Also it would cause less ground contamination, because majority of fuel would burn in air, instead of that detonation dispersed unburnt toxic fuel all around the impact site.
