Um .... right .... the wind came from the northern half of the sky ... so the angle doesn't matter ??
Then what of your claims about 'wake effect' which
do depend on wind direction ?
271° is "from north of the building" and 89° is "from north of the building" . Would your 'wake effect' on the smoke from wtc5+6 apply equally in both those cases, and all cases in between? I think not. Construct a graphic to show this 'wake effect' picking up WTC5 smoke onto the W side of the WTC7 face with a 271° wind eh?
A 271° wind is hitting the S side

An 81° wind is leaving the 'wake effect' on the wrong side of the building

The wind direction is vital to your miserable little theories.
You cannot just 'say stuff' and have it be correct because you want it so, achimspok. Science doesn't like that.
Meanwhile you continue to lie about the direction of the plume (blue line) in your satellite photo and (new lie) that late afternoon shot of GZ smoke clearly passing behind buildings to the SE of WTC7.
You have no evidence, achimspok. You rely on pre-existing belief and the torturing of facts and science to beat the real world into agreeing with your beliefs. You make up 'stuff' hoping that one small thing might be right, and that that will make everything better.
