Airburst mode causes grenades to explode on first impact, not at specified point. And I don't mean the scenario when it hits something *before* that point. If your target point is in the air, the grenade doesn't explode there but continues its travel until it hits something, sometimes, WAY further. Now that *is* useful, and I was wishing I could do just that more than a few times before I discovered it, but it is in no way what the description states.
