Just This Once... Your reply reveals remarkable naivity with regard to the introduction of complex new pieces of kit into service. While working with the world's benchmark CATOBAR operator, the FAA pilots (and other personnel) are gaining vital 'hands on' subject matter expertise which is already being invested in restoring the RN's capability. If you believe their contribution is limited to flying an aircraft, then you are sorely mistaken. So open
your eyes "Princess" and try not to let your prejudices blind you to the facts quite so much in future.
