...humans on time travel excursions? The different types of ships could be just different companies models. Likes cars have different shapes :DMuch like we go to see apes at the zoo or go to visit the pyramids.Mike ufos have been seen throughout the ages.Do you think the 'driver' of the ufo or the 'flight attendants' would be able to leave the ship or even know the workings of the schematics of time travel machinery?

Well considering it would take an alien to travel at the speed to visit Earth from an alien world, and travelling at the speed of light would cause a time effect you never know, it could happen.

If this is the 'theory' that t the gold plates with strange geometric designs came from a time-traveling craft that crashed thousands of years ago in southern England is nonsense, they are just archaeological finds from ancient burials ~http://www.solvingstonehenge.co.uk/page3.html
