YES. Turbo propeller aircraft are state-of-the-art and are an average seven years younger than the jet aircraft of major airlines. Jet engines power all regional aircraft, whether a turboprop with propellers on the outside, or a turbofan with fan inside the engine casing. Turbo props are the most economically efficient aircraft for flying shorter distances.
The U.S. commercial aviation system, regional airlines included, is the safest mode of transportation in the world. Moreover, the safety record of regional airlines equals that of major airlines - including pilot training and the rest requirements, safety equipment and dispatching procedures.
