Might be an idea to give Cafe Pacific a heads up as it's a sunday and Cranfield would otherwise be pretty quiet
I'll be asking for definites (although if you don't know until literally the last minute then just turn up anyway) on the 12th. Aircraft reg and type, POB's and whether you want fuel or not. I'll give the caff a ring and let them know they are going to be invaded. I'll be wanting to call Cranfield on the Wednesday before as the five day forecast will be out and we will have some idea of what the weatherage is going to be.
It's worth giving the plate a heads up (which of course you were going to do anyway) as it's not standard overhead, they have clattercopters and other offences unto God.
