N643CR - Charlie Monfort’s Challenger (He owns the Rockies)
TAG773- B727 that follows Charlie’s jet around. I am not sure if this plane carries the team or possibly equipment.
I think the Rockies actually charter a Frontier airlines jet, but I am not sure. I will watch tonight (both the Diamondbacks and Rockies are flying to Denver tonight), and will post more info if I find it.
Go Rockies!! 8)
