A friend of mine sent me this video about Steve Saint's flying car (yes, he's that Steve Saint - the son of missionary martyr Nate Saint who was killed with 4 other missionaries on January 8, 1956). I had heard a few years back about some related projects that he was working on. It looks like he's made some good progress toward making some of his dreams a reality.
This is a beautiful illustration of using your imagination to the glory of God and the good of all peoples! Make sure you watch to the end to see his real reason for inventing it.
