In the early 1980s Chalk's International Airlines owned by Merv Griffin's Resorts International had 13 Albatrosses converted to Standard category as G-111s. This made them eligible to be used in scheduled airline operations. These aircraft had extensive modification from the standard military configuration, including rebuilt wings with titanium wing spar caps, additional doors and modifications to existing doors and hatches, stainless steel engine oil tanks, dual engine fire extinguishing systems on each engine and propeller auto feather systems installed. The G-111s were operated for only a few years and then put in storage in Arizona. Most are still parked there, but some have been returned to regular flight operations with private operators.
