Flying Dinos from Ulysses Ang
In Mission 2, notice the plane going towards you while you destroy the cream-colored Stealth Bomber jet…a flying dinosaur. Of course, you can shoot it and it explodes.

Bonus 5% Life from Ulysses Ang
Shoot the flying dinos and get a 5% bonus in your ship’s life. Currently, I know of two locations of these flying dinosaurs: mission 2 (after the cream colored stealth bomber) and mission 6 (after the ship that looks like the ship of Clint Eastwood in ‘Firefox’).
