Well I've followed the Titor case myself some years now and still have not concluded if I believe it was real or a hoax. I have not seen any evidence towards either, no people have come forth and said they were behind it nor have anyone been verified to be behind it by anyone else to my knowledge. I know a book was sold retelling the story, and I know an amateur movie was made about it, but I don't think either of these were linked to the person behind the Titor story, at least I've not seen any evidence towards that.
At least one thing is for sure, whoever was behind it had great scientifical knowledge and if it was a hoax it was quite an elaborate one, I particularly found the manual for the time machine itself interesting as this shows that whomever made it had more knowledge than most people in regards of physics etc.
I did consider it perhaps was a group of people involved in making up the story, for some future commercial purpose such as a movie etc but that never happened, except for the amateur movie mentioned above which was to all my knowledge only inspired by the event and had nothing to do with the person(s) behind the story itself.
If it was a hoax I wonder what purpose it had as he did disappear exactly on the time he had said long time before, and never came back to get more "fame" etc after that, nor have their been any other obvious reason for making such an elaborate hoax if that is what it was. A lot of time and effort must have been put into it, making all that manual, photos, coming up with the whole story and keep going on for such a long period of time etc.
I must admit I found it a bit funny/peculiar that his time machine was actually a car just like in the Back to the Future movies

And yes he made a lot of predictions that so far did not come true but we still got some years left to see about the rest of them, and also have to take in consideration both the possibility that the timeline was changed, and also that he possibly came from a parallel timeline/universe more different to this one than what he thought. Also, he did admit he was working for the governments, so if he was real, he could have come up with some things that were not true on purpose for various reasons. Of course he could have done that even if he wasn't working for the government but still real as well.
What I DO know however is that time travel IS possible as I've done it myself, and the way I did it confirms his multiple timelines/parallel universes claim, so I also know that part is real. And because of this, and the fact I have not seen any evidence that he was a hoax, I'm open for the possibility that he was for real, but as stated that is something I do not know nor really have made any opinion about.
When it comes to my own time travel experiences I think I've written about them here before so I'm not gonna get into that now, besides that's not what this current thread is about anyway and even if it was I'm too tired to write more at this moment =)
