There was an interview with the crew, taken by КП (Komsomolskaya Pravda :o) newspaper,
the Capt. referred to "two similar accidents in the TU history" - one in China - as noted above - and one sorry forgot where else.
But then the Capt. added he is not sure that's the same bug, as "both those two flights were in auto-pilot mode - while we were not!"
Then he said, naturally, "the commission will sort it out"
And separately noticed it could be those 3 wires set - red, green and yellow, connected reasonably, "while the factory must have planned that someone connects them not according to colour but according to the manual book" "it is very mis-leading and a protest was sent to the maker pointing out a normal person does not deliberately colour wires same colour which one wants NOT to be connected!!!"
But about causes he spoked briefly "commission" etc. their matter
Mostly about his impressions :o))))))) of the dis-obedient plane on hands.
That they wanted to go back home at once :o) but managed only from the third attempt. Apparently it only lasted 13 minutes, during which time they did 3 landing attempts, intense 13 minutes.
He said what scared him is all the devices kept showing that all goes OK - before the take-off and during the mad flight.
The "bort-engineer" crew member was saying he only watched the engines that they shouldn't save god stop was focused on that.
