Much of Delonge and TTSA's credibility comes from their release of video from the "Nimitz Incident". F-18's encountered a 40 foot long tic tax shaped object. Delonge and TTSA also interviewed the former F-18 Pilot and CO of VFA-41, (Dave Fravor).
A nice animation and some of the Pilot's interview is here:
