Chances are this never happens but I thought I'd ask. What if Fight for life and Air life are all busy? I know both have more then one aircraft. But if for some odd reasion all are tied up. Who backs them up? Do you call in one from Greeley? Maybe the springs? Or does the national guard help?? Again I am sure this never happens, but what if? Are you just SOL? Or would you call a ALS bus?
