Where have you seen this? Are you talking about actual photos/video or are you talking about the graphics depicting the events that have been shown on some of the news channels?
I've looked at lots of pictures and seen (and taped) about 25 hours of TV coverage since this incident began and I have not seen one single picture or video where you can actually identify the plane as belonging to United. In most of the shots, the plane just appears as a black silhouette. In the one photo where you see the plane right before it hits (shown here)
how can you tell it is one of UA's planes? I don't see any "very distinguishable features of the United livery". All I see is a silver plane. Is there a photo I've missed?
Personally, I'd rather have United (and AA, too, for that matter) use the money to hire well paid security screeners instead of contracting it out to these firms that pay people $6.00 an hour who most likely will be gone in three months for a better job. JMHO.
Again, the difference between AA and UA is that there's very limited video with AA's livery in it -- I've only seen one video of the first plane.
I've seen the one video of AA 11 crashing into the WTC, too, but you cant see the livery. You don't see the red, white and blue stripes and you don't see the AA logo on the tail. All you see is a tiny silver plane (beacuse the camera only zoomed in after the aircraft had penetrated the building to show the smoke and flames).
UA's livery was shown and again and again, from every possible angle.
United's plane was shown from every angle again and again, but in none of the pictures (that I've seen) do you see the words "United" or see the stylized "U" on the tail.
The last plane to be painted into the current livery rolled out in 1999.
I'm confused. Has United not received any new planes from Boeing since 1999? If they have, then those planes would be rolling out in the current livery.
