My utmost apologies (genuine ones this time - not the usual sarcastic variety) - I was probably told about this in the Top Level Messages or similar during either SDSR (when I was OOA) or during Ellamy (when I was OOA).
Either way, I was busy and I lost all interest in my career at about the same time!
More than happy to be corrected and glad that we have sorted out all the TORs for our airships. One assumes they run 4 Typhoon FE@R each?
