Looks to me like both engines were working??
I'm sure the press was talking to someone that thought they knew what they were talking about...... both props on both sides are curled up like they would be if both were under power. If one engine quit wouldn't only one would be curled? Even a windmilling prop would most likely stop on the first blade to hit the ground and only curl one side and it would most likely be curled under the cowling.
:dunno:. I wasn't there, so it's all hear say. It may have just been a rough running engine and an abort. Who knows.
