The JetStar's competitor, the prototype McDonnell 119/220 is still
stored at El Paso - a sort of mini DC-8. Changed flights at El Paso around 20 years ago, if I'd known it was there I might have whipped out of the terminal to to take a peek! Unfortunately we landed/departed on R/W 22 from which it would probably have been invisible...
Always liked the JetStar, like the GII/GIII proper GA iron!
