Data 7.1
Just inside the front gate, you'll see a vehicles are with a few APCs and an entrance to the hangar. On the left side of this area will be a green overhang. Get up on top of that to find this Data.
Data 7.2
Stick to the right side of the hangar and climb up the boxes as you make your way to the back right corner. The second tall stack just before the corner will be lined up perfectly with the propeller of the plane. Climb to the top, hop to the propeller and then you'll find the Data on the left blade.
