It was so clear that if someday one of the engines fail, there is no way to recover it, specially during summer..
Dude! IF one engine fail?! According to what i heard engines failing is something routine in this type!!!!!!!!
Everyone on this project knew this was a failed plan to build this **** but due to some ego BS they keep going ahead with this crap!
I think President Ruhani did a good thing banning this type from flying and I hope it stays that way for good!!!!!!!!
