An air cargo drop mission can be quite demanding, especially if conducted at night.
The thing becomes much more challenging when the flight takes place over the enemy territory where there is a residual risk of MANPADS (Man Portable Air Defense Systems) or small arms.
On these missions, not only pilots but all the crew wear Night Vision Goggles, and use the side windows of the plane to spot any sign of hostile fire.
