Fifty years is quite a milestone, the label Golden Anniversary reflecting its value. Our preparations for its celebration has been a fascinating learning experience — and a humbling one. It revealed to us on the staff the scope of this publication’s coverage of the vertical-flight industry over five decades. It reinforced our understanding of Rotor & Wing International’s vision to cover not only the daily developments of the world’s industry, but also its promise. Those preparations also reminded us of the essential role that you, our readers, play in supporting our efforts. We hope this issue captures the history on which we have reported since 1967 and the promise of this industry in the next 50 years. We thank you all for sharing your expertise over the last half century and for the loyalty of your readership through past years and those to come.
