y’all may have noticed that I tend to provide my rationale for a guess after the expert who posed the question indicates that the guess was wrong … maybe I should just leave well enough alone rather than letting my analyst personality come to the fore; I certainly don’t mean those remarks as anything more than an explanation of my thought process, and I once again apologize to all concerned for the appearance of criticism

as for the Bonus Question, I believe Emerald operated the FH-227B turboprop, but I’m drawing a blank on another pure jet type
