I would rather have a 'Star Trek' style space ship
Just as unlikely but a lot cooler.
You would get a lot more out of Heinlein, who wrote ficiton honestly and had a much better feel for space travel than Adamski.
You should find Rudy Rucker's 'Saucer Wisdom' for the best review of saucers and their impact on people.
You shold read 'Watch the Skies' for an excellent history of the ufool movement, in which Adamski is a sort of a founding player.
