I've done a rebuttal to the german version of the BBC's "The Third Tower", called "Das Rätsel des dritten Turmes" broadcasted by german second television channel ZDF and their "ZDF history" format on 08/09/07.
I put all the infos we gathered together into it, and it's quite a devastating result for the ZDF- almost every claim they made was false, they used some of the same tricks like the BBC like the cut and fit for their needs of the Jennings testimony, but refused to use others, like the victims-mockery if you ask questions and refuse to believe the official narrative.
It's a 111 page .pdf with 3,7 MB, the making of the script (which the ZDF denied it has and so couldn't gave me) alone took me 4 days in a row.
My wife actually said I'm crazy. ;)
Anyway: here it is, only in german so far (maybe a translation follows)
