Might have been the third attempt at the approach for N115WF. At the 27:15 mark of the 1830z recording, the crew acknowledges an instruction to intercept the localizer. FlightAware track shows an overshoot. Then at the 28:10 mark they are instructed to fly heading 120, and are vectored around for another attempt.
At the 28:24 mark, an arrival hold is announced for Aspen, presumably to allow an opportunity for the dozen or so aircraft waiting on the ground to depart. 5WF is the last aircraft scheduled to arrive before this hold becomes effective. During its final attempt, the wind is reported as 330 degrees at 16 knots, with gusts to 25. That's a significant tailwind component.
Interestingly, around the 7:15 mark, Dotcom 2541 goes missed, and then Flexjet 339 has its approach clearance cancelled shortly thereafter. At the 14:45 mark, Gulfstream N7HB breaks off the approach to "resolve an issue," eventually diverting to Rifle. This requires the trailing Learjet XA-VAL's approach clearance to be cancelled. The re-sequencing of these aircraft appear to cause Skywest 6425, at the 18:57 mark, to be notified of a delay, resulting in that aircraft diverting to Grand Junction due to fuel status.
A difficult and tragic day for all involved. Thoughts and prayers for the Challenger's passengers and crew.
