why yesterday so many ambulance on CTE? 
busy day for the boys and girls?
I guess it was an RTA before bradell exit requiring 3 alphas.
Most likely standby case since if 2 alphas would be more than
enough for a few papa 2s.
the reason is because the stretcher for the new alpha is spoilt
so therefore the new alpha is deemed "under servicing" status till
the stretcher is fixed..
You know about 231 very well hehe.
I bet there are some lurking medics here haha.
