The achievement description says nothing about the sensors. "Survive" the assault basically means just kill everyone that comes.
Yeah, this is almost story related if you kill all enemies. Maybe say something like...
"After defending the the two sensors in this mission, there will be a final switch you must activate to open a portal. Before doing so, make sure you eliminate all enemies. The achievement unlocks after you press the switch."

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.
Thanks for pointing this out. The reason some people have not been getting this achievement in one warthog is likely because of time difference. When my friend and I got this, our console times were different (even though we live in the same state). I think the time is based off your internet provider. I was about 50 seconds ahead of him time wise. This would mean that if I got mine, he would not get his because his time was not matching. Maybe someone can try to do this and see if the achievement can unlock for a passenger/gunner?
