I am so sorry to cause this. . .All I meant was that the Tu-154 has many accidents due to system failure where there was no way out of the situation. and they seem to blow up some times (I'm not quoting the Ukrain missle practice) due to engines etc.. .Also I meant the Iranians getting rid of the TU's anyway. . .They had a good saftey record till the sanctions, trigger happy yanks and the Russian shopping trips...
