This achievement is for completing Hover Headway, which is an "Against The Clock" level, without touching the floor. To unlock the level, you have to obtain 20 medals leading up to it. I've included videos in which I obtained Gold Medals (3 medals) in each "Against The Clock" level.
Just to clarify, you do not need to get gold medal on every challenge leading up to this as you only need 20 to unlock the level for the achievement. Achievement Level - Hover Headway
If you touch the ground, there will be a "failure" noise that plays. If you hear this you'll have to restart the level.Speed WayPlans For Fans
