You can earn this Achievement while accumulating rolls for the 20-roll Achievement.
Select a narrow course, like San Francisco or Long Beach. When you approach a chicane (zig-zag), clip the wall to send your car into a roll. If you catch it right, you can get a good airborne flip end-to-end. If your car stays airborne for 1 full second before touching back down, you will unlock the Achievement.
The Achievement will unlock as soon as the one second has passed, and completing the race is not necessary.
