G4 4205 on 9/28

[does this plane go to paris]

Last night, 9/28, G4 had a flight from RFD to SAN #4205, as it approached SAN, it appears that it missed it's landing and diverted to PSP. They turned it around after a short time and it landed back in SAN at 1247am.

There is a lively neighborhood debate on another site about the flight and how it disturbed many folks. I'm trying to interject a few facts and would like to know anyone has info as to the reason why it diverted. Thanks.
