WHAT IS WRONG WITH THESE STATISTICS?

Ladies and gentlemen,
creatures from the darkside,
I have a puzzle for you to solve.
It comes in two parts.

First open up the FAA N-number registry page.
http://162.58.35.241/acdatabase/NNum_inquiry.asp

Next go to the BTS site
http://www.bts.gov/programs/oai/airline_ontime_statistics/
and scoll down to where it says DETAILED STATISTICS
Click on the arrival or departure statistics.
Click on the actual arrival or actual departure time.
Click on a major international hub airport.
The September 11 arrival or departure airports
or DCA Reagan National are all excellent choices.
next click on American Airlines and just about any date that comes to mind.
Say September 10,2001
or perhaps the latest available statistics date which would be April 30 2004.

Very good.
For those of you who have difficulty following such directions,
Here are the results for September 10, 2001 and also April 30, 2004.
Take a look at them and then tell me,
WHAT IS WRONG WITH THIS PICTURE??

Can you see ANYTHING wrong with those statistics?

Here is one hint.
This thread is about the pilots and the ..... PLANES!!!
YES you got it!!!!
But what exactly is WRONG with the planes??

HINT:
The answer can be found on the FAA N-number registry.
http://162.58.35.241/acdatabase/NNum_inquiry.asp
Look closely at the N-Numbers above.
Some of them are mostly NUMBERS
and some of them are mostly ..... LETTERS!!!

Now be a dear and
punch in a few of the N-numbers that are mostly NUMBERS
and then
punch in some of the N-numbers that are mostly LETTERS.

Then come back and tell us all what you just discovered.
Do hurry,
some of us are holding our breath in anticipation.

And if you like THAT riddle,
and tell me what is wrong with THAT picture,
then maybe You can help solve ANOTHER MYSTERY.
