787 smoke venting from E/E bays
As written in a previous post, the reason why it was possible to vent the smoke in cruise, but not on the ground is simple.
Venting is done by an overboard venturi, which only works during flight (it is only used in cases of failure, normal E/E cooling is accomplished using electric fans). On the ground, as in the Boston case, this type of venting cannot work, so smoke was able to enter the cabin.
Glad rag,
The RAT sits under the wings, but feeds into the main circuits in the forward E/E bay.
