This is slightly unusual topic, so let me explain. Aside from the fact that some of y'all were old enough to remember when the 727 first flew, people's tastes change.
A few of my examples:
L-1011 over DC-10. It used to be I didn't care for the L-1011 whatsoever. I was a DC-10 man through and through (okay, DC-10 boy is more like it, this is before the MD
-11 was introduced to service). I didn't like the L-1011's S-duct at all. But reading a book by a guy who flew for a week on one of Delta's L-1011s, then the Queen of the Fleet (it was ship 723, 763, something like that), changed my perspective totally. Once I realized how unique the L-1011 was, and how fine her engineering, my perspective totally changed. I cared naught for the DC-10 after that, and even the MD
-11 I viewed with suspicion as an upstart with bad landing qualities.
777 and MD
-11. I admit that I've had my dream airline (Fleetwing Air Lines), and for a long time I had the MD
-11 in the fleet roster, even knowing that the 777 was the superior aircraft. Finally, I had to admit that having MD
-11s was romantic, but not practical.
over CRJ. My first RJ
flight was on a Comair CRJ, and I thought they were pretty neat. Especially since my last Comair flight had been on a Brasilia. But the ERJ is roomier than the Brasilia, and I prefer the 1-2 seating and the larger, better positioned windows over the CRJ.
However I refuse to give up my MD
-90s and 717s in favor of any 737 or A320, ever. Who cares if they need more maintenance...?
