Air ambulance:
WBA - Air Albatros operating under the Medic'Air International banner
This ID is being used by F-HFMB, an FA50 of Ixair SAS, operated for Medic'Air International
The FAA lists WBA as French company Air Albatros. Medic'Air call the FA50 their Albatros, so I guess it's the right company.
