Juan Brown (airline pilot flies in right seat 777) does an excellent job describing the incident.
The bigger plane was on a long final to the LEFT runway. The Cirus was downwind on the right, shorter field when he turned base and possibly was turning final for the LEFT runway when he should have turned final for RIGHT earlier.
It was obviously the Cirrus aircraft's pilot's fault from what was presented. The ATC had alerted the Cirus pilot to both traffic but there may have been confusion on his part.
A student pilot doing HIS FIRST SOLO was following the Cirrus and will always have a good story about his FIRST SOLO!
That youtube only has a 12 minute commercial.
