You probably don't know, but RAFA organizes a memorial every year on the nearest Sunday, to which the USAF sends a representation from RAF Menwith Hill, with a senior officer laying a wreath. I haven't been myself, but I understand many local dignitaries attend this annual service of commemoration, including the Lord Lt for S Yorkshire. The BBC has made no mention of this. I believe this has upset the local RAFA a little. The campaign to have a flypast on the day of the anniversary threatens to put a spoke in the wheel of arrangements made thus far. Sunday itself is a no fly day at Lakenheath, which is no surprise, particularly at this time of year.
Perhaps expectations need to be managed.
