The document discusses how the cartoon The Jetsons, which featured George Jetson commuting to work in a flying vehicle, inspired current efforts to develop real flying cars. It describes several companies working on prototypes that could be available to the public by 2021, including the Terrafuga TF-X which would be able to vertically take off and land and reach speeds over 200 mph, as well as competitors like the GF7 and PAL-V models. While flying cars were not achieved by 2000 as depicted in The Jetsons, the document suggests that within a few years we may start to see neighbors commuting by air as shown in the cartoon.
