Ladies and Gentlemen:
There has been much bashing of the DC-9/MD-80/MD-90/717 and the 737. For simpicity I will refer to the DC-9/MD-80/MD-90/717 series as the DC-9 and the 737 series as the 737.
Bashing either of these aircraft is foolishness! We all have our favorites and our least favorites, be it the seat size, the engine placement or the general asthetics. Bashing the DC-9 or the 737 is foolish, we all have read the complaints of the "uncommanded rudder movements" on the 737 and now the "Jackscrew" on the DC-9. Has anybody noticed anything, if you are taking a trip chances are you will be on a 737 or a DC-9! Both of these aircraft are the workhorses of most major airlines! The 747 series in total does not have as many cycles as the DC-9 or 737 series; the long haul aircraft spend most of their time cruising not making 100 mile short hops. The slightest little defect in design, over time, will surface faster than a design defect in any other aircraft. To say that either of these aircraft is bad is wrong and foolish! I have my likes and dislikes of both of these aircraft, NONE of my dislikes are in design! Both of these aircraft are built like trucks, they are the workhorses of the airlines and have the records to prove it. I don't have the statistics in front of me but I believe there are more 737 and DC-9 series aircraft in the air than any other type (I'm pretty sure, I could be wrong my numbers are old) some airlines use them almost exclusively (AA, WN, ME) it's not because they are cheap, they're best. The Airbus people have valid points, however there are more DC-9 and 737's flying than A320, A319, A318's (the nearest competitors). There's the facts, discount them, challenge them, PLEASE, try to prove me wrong. If you've flown, you've more than likely been on more 737 or DC-9's than anything else.
