Re: if Hospital Wing 7 is based in oxford MS ....

Hospital Wing 7 could also be the 'base brand' or the 'medevac base
ID' used by the certificate holder for the aircraft or the medevac
program - actually its a mixture of brand and specific ID - isnt it

what if HW7 is flying helo N1234 or Monday but is flying helo N5678 on
Tuesday - what is HW7 - its not really the helo ID - its the ID of the
helo that flies those people out of that base on that day

same goes for any fire truck - Engine 1 has Larry moe and curley on
monday - and on Tuesday it has Raquel and Sarah and Marilyn - and what
if they are using a spare piece on wednesday - so "Engine 1" actually
means quite a few different things - but in the dispatchers eye - its
all the same - its the unit that takes calls from Station 1 - end of
story

if you look at wildweb - this idea is fully in play now at some
locations - they list every vehicle and they list every crew member
assigned to that vehicle - both on duty and off duty and on unit and
off unit
