Thanks for the great job and time, Chris
I'm working a video about this event but I'm not sure where exactly they collided. I've been diving through the PHX layout chart and can't understand how Frontier pushing back on Gate 25 can collide the Southwest taxiing 'south route' (Guess this is SIERRA taxiway to transition from north to south ramps?) I'm missing or misunderstanding something for sure.
Appreciate the help!
EDIT: I was looking at Gate A25 and not Gate 25 on Terminal 3. Now I see the possible pushback route of the Frontier and Southwest coming over just on taxiway C... how couldn't they see each other? (I mean tug and SWA pilots)
