Mmmm after lots of testing and hours of sifting through data I can only conclude that what you see in a movie is fantasy lol, they did build a jet powered truck for the movie and it did actually work, but 200 mph is a long way from breaking the sound barrier and visiting the 8th dimension, E.t is still with me and thinks we should finish the truck by getting the jet engine working and go back to the dry lake bed and have some fun, but we will not be straying from our course and heading towards a solid rock wall in the hope we have enough speed and a working mystery gizmo that will allow us to pass right through and emerge on the other side completely un-damaged after a quick visit to the 8th dimension, still hoping there is going to be a sequel though, thanks for looking love Kiiko and for now E.t
