You may not believe that but "Moscow TV" (even some chauvinistic channels which I hate) never elaborated on this idiotic conspiracy addressing the "attempt to shoot down the Putin's plane".
Regarding the "Russian invasion": The time for that option has gone long ago. Putin had already announced some 2 months ago he would not give such an order. Also the Russian parliament withdrew its formal permission to the president to use the military force abroad (read, in Ukraine). If they really needed that, it would be done in spring and took a couple of days.
I am not a fan of the current policy being carried out in Russia, but there is understanding here that "the stakes we are gambling are frighteningly high".
IMHO, now those rebels are a problem for Putin and actually he never liked them much. Recall that when they announced a referendum to separate from Ukraine (in March) Putin said "do not do that". They ignored his advice and arranged some chaotic voting. I am sure he was angry. Especially as the Ukrainian pres. candidate promised at that time he would not ban the Russian language in that part of the country (the point that actually started the fire) and that seemed enough for Kremlin. Then the rebels were asking for a military invasion in south-east and the answer was again "no". After that some voices were heard from there that the "rebels condemned Kremlin " who "let them down" and obviously it was not appreciated.
