I have a number of old timetables for that period and was also working close to BHD and have pages and pages of spotting records. None show an Air UK service from BHD. Air UK did fly F27's from BFS to LBA (fly the blue plane was their advertising slogan. I am therefore intrigued that I missed the BHD F100. Can you provide any futher information? My records show that Loganair BaE 146's (registration sequences such as G-LOCA) and Capital to LTN (SD360 to LBA) also with BAe 146 (G-OSKI and G OSUN I think) were the first regular jet services to BHD. I do have a record of an Air UK F27 (G-BLJF) at BHD on 1 November 1988 (I think operating for someone else). Jersey European was still using F27's and SD360's at that time
