Just done some digging via some sources. Apparently my application was first vetted by OAA, approved and then forwarded to the BA side for their approval: which it didn't receive for whatever reason.
As for the actual text of the email (which, for those who aren't following closely, didn't include an invitation to go up there and spend 100 grand of my own money) the unsubstantiated speculation amongst less well-placed sources (and I emphasise it is just that) is that BA might be displeased with the FTO using a BA email address to drum up private business and asked them to change the text of a pro-forma email.
Hope to find out more soon, as only this morning have I found out that a chap I knew in my days as a Spacey coming to grips with the mighty Grob Viking is now nose-bleed high at OAA. I might wait until the dust settles before I contact him for the first time in nearly 20 years.
