You work in the air force of the task force, currently you were in the sky on a mission with the task force keeping eyes up there and dropping bombs onto enemies

As you were flying in the aircraft, you were given a direct order from Price to get a higher position so you are not seen by enemy aircraft, you were to high and needed an oxygen mask.

As you got your oxygen mask you slipped it over your mouth and nose, but the oxygen was replaced with sleeping gas, you didn't notice it till you started to doze off which lead to unsteady jet driving to which you then tried contacting one of the members of the task force
