Crash into a flying airplane
To complete this trophy, there are several ways, many of which end so that you exploded by plane. Even if that happens, the trophy will be unlocked.
We went to the airport in Islas Intichayes and grabbed a small jet. Then roll on the runway, slowly. If you see another plane approaching, accelerate and take off. Just head for the other plane and ram it.
If you do not explode immediately, jump off and save yourself.
