Ian,
Know I am confused, just checked the d/b and there is no SE-RIB in the d/b. The used to be an SE-RIB but that was an A319 which is now in the Philippines. G-EMBY used to operate for Flybe before it was WFU and entered storage.
There is an SE-RAB in the d/b, I dont know if this is the one you are discussing, which is c/n 145453, which version of the d/b are you using?
Alan
