I wish this was a joke but it is not: this Pakistan Airlines ad appeared in the March 19th, 1979 issue of Le Point (and surely countless other publications).
As 2spare.com points out, the shadow is in pretty much in the same place as where the planes hit on September 11th, and there’s no way the shadow should be that big unless it’s seconds away from hitting the towers.
Cue the conspiracy theories.
