Listening to the LiveATC.net tapes, Skywest 5869, N796SK, a Canadair CRJ-702ER from Aspen landed on 34R, cleared at high speed F9, taxied back on F, cleared to enter the ramp at CS.
They stopped on F before going very far back south, said they had an electrical problem and the ground controller reported seeing flames. Pax evacuated before the first trucks arrived, fire quickly extinguished. Sounds like 65 souls onboard on one radio call by the ARFF crew. Another count was announced as 57 adults, two juveniles. No injuries reported.
On tower, usual emergency shuffle, one plane offered late runway change, wisely took the missed instead.
Expected media reports that the 'plane was on the tarmac' or was 'taxiing on the runway'.
