Hack the plane and search for the Black Box
When you catch up to the plane, you have to get right near it in order for the hacking to commence. After you get close enough, bring out the SecuroServ app on your phone and you should see a percentage on the screen. Keep up with the plane as this percentage starts to rise. If the percentage stops going up, you need to re-situate the Tula to be closer to the plane.
Once the percentage reaches 100, the plane will be hacked and your next task is to blow out one of its engines. This can be tricky, as the Tula’s machine gun is wobbly and inaccurate. However, you only have to shoot one of the four engines to take the plane down.
If you manage to do so, the plane will crash and end up in a lake on the ground. Descend with the Tula and hop out once you’re close enough to the crash site of the plane. From here, head underwater and use your sonar equipment to find the black box. It’s located in the front section of the plane, so you have to go inside the cockpit to find it. This requires a sticky bomb to blow up the cockpit doors.
With the black box in hand, rise to the top of the lake and find the nearby dinghy that’s been provided for you.
