Got significant air in the Warthog at midnight in mission 2.
Campaign Mission 2 'Requiem' specific. Online not required.
Can be obtained on Easy+.
Use 'Mission Select' after initial Campaign playthrough if missed
Be the driver in a Warthog and achieve significant air when your console time is at 12:00 am. Only the Driver will unlock the achievement.
It's been reported that the achievement may take a couple seconds to unlock.
I did this with my brother by changing the timezones. He drove and I was the passenger, not the gunner, and when he did the jump, both of us received the achievement.
