The Eurocopter AS355 Ecureuil 2/TwinStar is an improved, twin-engined variant of the Eurocopter AS350 Ecureuil/AStar. During the San Diego Incident, it is used by the Police in an attempt to take down the Bull Tyrannosaur during its rampage through San Diego. If not for Sara Harding‘s tranquilizer, they may have succeeded in taking down the Rex.
