The best part is, even if he claims that the above clip is fake, it still means he needs a new explanation for how exactly it was allegedly faked.
If I recall correctly, he claims it was newly faked and inserted into the film library they now hand out, whereas the package they gave out when he got his didn't include that.
Two problems with that. First, Sibrel's duplicitous editing isn't limited to just that one case. We can cite a number of examples from his film where he simply edited away the parts of the record that contradicted his claims.
Second, there is a prominent example of pre-existing complete Apollo footage. While Sibrel was still in high school, geologist Larry Haskin (WUSTL) obtained the whole Apollo video library from NASA and made VHS copies of it, including Apollo 11 and the clip Sibrel said didn't exist until NASA needed to discredit him. Copies of the Haskin tapes are rare, but they confirm Sibrel is mistaken about the smoking gun clip that proves his dishonest editing.
Comments disabled on his video, maybe so no one actually involved with the production could call him on his crap.
