Your going to have to be more specific. I’m not conversant in all the technical jargon.
The aircraft is flying in direction X, the axis. Most debris is found in a path along direction X. Some debris is found along direction Y, say at X + 60 degrees, as if a missile had struck to create the off-axis debris.
With a quick look I can’t find any backup, but remember seeing this along with a chart back at the time.
The area in question is the tan debris field that resulted from something striking the 747 just after the last transponder return at 31:12. That had a passive radar signature clocked over Mach2 and took out seats, passengers, luggage, papers, etc., all found in the "crosswind debris field," including heavy items blown back beyond the flight path. A ground-to-air rocket motor was later recovered by a fishing boat in this field, photographed, but then "lost." The "red zone debris" contained wreckage from the nose: seats, passengers, luggage, papers, carry-on stuff. . . Etc. The green are is where the main body of the 747 fell after a ballistic trajectory from the initiating event. . . calculated by the USS Rude which sailed directly to that spot based on those calculations, and found the sea burning from the splashed in 747 and floating debris.
