RE: HRC?? Who are they??

I’m currently working on a searchable database on my web site which will contain all airline info like IATA, ICAO codes callsigns etc.
I’ve found sites that list some, but they list them in a certain order and it a problem (eg if they list in alphabetical order of the airline name and you want to know who uses HRC then you’ll have to scan the entire list to find the answer)
A database where you can search any field will be a lot easier to use. May take a while to set up but I’ll let you know when its done.
