The plane is only about 100 yards in the distance, so run ahead and take cover behind the green car, as more enemies will run out ahead to stop you from reaching the plane. Look on top of the raised platform in the distance to find most of them. Eliminate the enemies with a height advantage first, and then look down to street level to find the final enemies cwering on the street. They will be using a turret to suppress you. Flank around to their left and stick to the metal highway barrier. When you are effectively behind them, pop over cover and shoot the red barrel to blow all of the remaining enemies up at the same time.
Run past the exploded turret and a cutscene will initiate. Your squad will make their way through the decrepit plane parts half-buried in the sand. Run over the dune past the wing ahead. Press up on the D-Pad to equip a silencer to your weaons. Shoot the enemy on the right first, and then hit the one to the left of the plane's turbine. With these two enemies in the back dead, look back to the right to find one wounded enemy and another enemy in cover ahead of the wounded one. Take out the wounded enemy first, as he may see his ally go down if you shoot the healthy soldier first, and then take the second soldier out with another shot. Although this target will be moving, try to go for headshots, as these are the easiest ways to ensure that you won't be detected on your approach to the plane.
Two more enemies will be standing behind a Humvee near the plane. Take cover behind the large cargo crate to the right and pop out from cover. Give one of your soldiers a kill order on one of the enemies, and take out the other enemy by yourself. Unfortunately, this will be the end of your little sneaking spree. Enemies will run out onto the wing of the plane and shoot down on you. When the enemies line up on the wing, focus on the bad guys to the left side of the wing first, as one will run out here with an RPG. If you let him get a shot off, it could very well be a premature Game Over for you, so be sure to take both of the left-hand enemies out before focusing on the two to the right.
Once the enemies on the wing are dead, a few more will rush out from behind the plane. Look just under the turbine (the one that's still attached to the wing, anyway) to see them as they advance. Take them out from a distance, anduse your squad orders to eliminate any who might elude your shots. With this wave of enemies dead, feel free to advance. Stop early, though, and take cover by the Humvee. Peek out to make sure that the coast is clear and take cover by the crate next to the plane's wheels. From this position, as long as you remain safe and there are no more enemies in the area, proceed to cover behind the crate to the diagonal front right of your current position. Enemies equipped with shotguns will come walking out of the steps in the center of the plane, and being too close to their entry position can be an easy way to die. Instead of facing them at close range, wait for them to emerge and then shoot them from a distance before proceeding safely up the stairs and into the plane. If you're interested in collectibles, note that the first piece of Intel is located just before you climb the stairs to get inside of the plane. Search in the sand underneath of the plane to the left to find it.
Once you climb up the stairs, immediately turn around, as all of the action will be happening behind your entry point. It might be helpful to equip one of the shotguns lying on the stairs, as you'll be doing some close range fighting in the plane. Proceed towards the openings on either side of the plane's hull and shoot the enemy on the other side. Proceed into the small room ahead and take cover, popping out to shoot the enemies in the next room. If you did pick up a shotgun, sprint out behind some of the seats and tear the enemies up at close range, vaulting over the seats when you need to advance forward. Note that you can approach this encounter in a different way by heading out onto the wing in the last room and grabbing an RPG. From your position here, you can launch it into the next room and take some of the enemies out before you go into the room. Just try not to launch it off anywhere near yourself, or you'll be looking at a Game Over screen.
When all of the enemies are dead in here, head into the next room. A short cutscene will show a group of the insurgents holding a member of the 33rd hostage. Take cover and do the only thing you can do; pop out of cover and kill all four of the enemies. As the soldier falls to the ground, he will implore you to find Conrad, who is still alive somewhere in the city. This will mark the end of the first Episode and send you and your squad exploring ever deeper into the ruined city of Dubai.
