I'm gonna throw this out there, even though flygirl will probably come in and chew me out for my opinions being to harsh for me not being an ATP or ATCS. Flygirl, sorry Im a "know it all" for knowing the position names.
Ok, I decided to listen to the audio myself in entirety and I found some more stuff that is pretty crucial. It's still not lookin' good for that Captain.
The new clip first starts off with Local West (Controller running 9R) giving USA1752 his initial taxi instructions off of 9R. Only Uniform to Papa.
At 3:00 into the clip LW tells USA1752 to follow the regional on Sierra, the RJ was the aircraft that caused SWA2570 to Go Around so he was exiting 9R at Sierra 1 and making a right on Sierra just after going around the construction areas that taking place on Sierra between S1 and S2. That's why LW said "I gave you taxi instructions" since he had already told him about the RJ that he wanted 1752 to follow for the sequence over to Echo.
Couple of people on other forums had asked "Why didn't the controller say hold short 9L?" It's because he didn't want him to hold short 9L! He wanted him to go the opposite direction. I'm only thinking that either pilot was confused and transposing Kilo as Sierra, if that was the case why weren't they looking at their airport diagram and you would think most USA guys would never be confused at Philly. Considering both Kilo and Sierra are the heaviest used taxiways at the airport and both parallel a runway. That's probably why he didn't see that RJ to follow, possibly because he was looking north up towards Juliet and Kilo...
The last transmission is where the position relief happened.
First time using this site, hopefully it stays up:http://www.mediafire.com/?61zs7vdmjyz
BTW, aevins don't worry about it. Even though I'm sure flygirl doesn't want to hear the truth about all the LAX, or BOS incidents that had been leaked or picked up by the media over the years.
