1 - a turbofan is a subset of jet engine, and there are no 738s running anything other than a turbofan. Actually, nothing in civil aviation that has a "jet engine" has used anything but a turbofan (or turboprop) since the early 70s with the exception of Concorde and some older business jets. (Turboprops are jet engines, too, to be precise, with the jet of exhaust gases powering the propeller.)

> Turboprops are jet engines They are certainly turbine engines, but I thought "jet" was reserved for those engines that propel the vehicle solely by their exhaust stream and bypass air. I am willing to be told I'm wrong, though.

  Turbofans are by your own definition jet engines. It's just that the bypass air is much larger.

    I think you meant turboprop there, but the distinction I notice is that one has all propulsive airflow inside the nacelle, and one does not.

      Agh. No, I meant turbofan, but I misread your post and actually completely agree with you - turboprobs are not jet engines.
