The Bell 212/412 family are two or four bladed, twin engine, medium lift utility helicopters manufactured by Bell Helicopter. The helicopter has the ability to carry up to 15 people or carry an external load of 5,000 lb. It has also been developed into a military variant as the Bell UH-1N Twin Huey.
During the 1997 InGen operations on Isla Sorna, we see two Bell 212 helicopters. The first was used to pick up Dr. Ian Malcolm and the others. The other can be seen in Roland Tembo‘s heroic exit. It is possible this is the other chopper mentioned when Ian asks about the other survivors.
