The Scan Eagle operator wasn't interested in houses 1 and 2 because they had already been cleared. So it's difficult to tell if houses 1 and 2 were on the video. From the air, every house in Haditha pretty much looks the same.
We might be able to do a match-up via Google Earth. I think cobra found the coordinates of the ambush site. The Washington Post also posted an aerial view of the ambush site which could be used for matching purposes.
If anyone wants to pitch in, we can use all the help we can get.
The suspected trigger house was 250 meters south of the ambush site (meaning where the IED exploded) and houses 1 and 2 were also south of the ambush site.
That might be wrong and the Taxi guys were possibly the lookouts.
Here is a guess of the positions, remember that all the action took place within a mile radius.
