Midnight Launch

4: Achievement Unlocked - Midnight Launch. Get significant air in the Warthog at midnight in mission 2.

Thanks again to achievement hunter, I figured out how to change the time setting so that even though I am playing at 3 am, I could get this.
The 60 seconds to get air is not that difficult. And the air does not even have to be that much. But as with the Reach 1M achievement, it is a matter of sitting here at the turn of the hour waiting to start making hops in a wart hog.

See ya!
