About 40 727's, all the -100 and -200 non-advanced are gone. They were all replaced with 200 "advanced". Thats an oxymoron if you ask me... an airplane thats on the average of 30 years old shouldnt have the label advanced in its name. Ever get to fly one? Was an easy fun airplane to fly, I spent 5 years in it before stepping farther back in time to the DC-8.
