Terrafugia's Transition flying car (or driveable plane) has stayed out of the spotlight since we caught a glimpse of it last year, but AOL Autos recently checked-in with the daring manufacturer to gauge its progress. Sure, the prototype has already scored a VIN from the National Highway Traffic Safety Administration (NHTSA) and an N-number from the Federal Aviation Administration, but it turns out the land /air hybrid is still awaiting complete certification by the NHTSA. Production dates won't be announced until the craft has been rubber-stamped by Uncle Sam, and that isn't expected to occur within the next 12 months. For now, suppliers are being lined up, and it's very likely that another prototype will be fashioned before it hits the assembly line. You might not be able to sit inside your very own Transition soon, but you will be able to see the first model on display at Cape Cod's Heritage Museum this summer.
