Concerning Airowlf....
After the show was cancelled the modifications were removed. The aircraft was repainted and eventually sold to the German helicopter charter company, Hubschrauber-Sonder-Dienst (aka HSD Luftrettung and Blue Helicopter Alliance), and given the registration number D-HHSD[1]. Airwolf, as a plain Bell 222 air ambulance, crashed in a thunderstorm on 1991-06-09, killing her three passengers.
