Could it not be that whatever caused them to go around for the first time also caused a second go around.
Previous go around accidents have proved that the 737 can be a handful in th go around and the pitch power couple can catch you out. This is the third accident of its type in Russia involving the 737.
The images look eerily similar to the previous incidents too. A video showing a high ROD, a flash following a very high energy impact, and highly fragmented pieces of the wreckage.
The previous two incidents (Aeroflot 821 and Tartastan 363) also happened very close to the airport perimeter.
