Sorry Victor. As I said in my initial post, I was unable able to find any details. The diversion of #5902 was possibly for medical reasons but I also have at the back of my mind it was due to an unruly passenger. Whilst I was seeking out the audio for this incident I came across the audio relating to the second incident in which it was evident that for some reason (not available in the archived transmissions) Southwest Airlines flight 485 had to hold short of the runway. It does sound like the same pilot; whether it was the same aircraft or not I don't know.
Thanks for your kind compliment.
