If your NRB for the day of the Wyton Reds display did not reveal them and should, have you kept the download? If so, there is an "R" followed by 7 digits at the beginning. AIS keep a file of all briefings. By advising them this number, they can call it up and should be able to see why it failed to show the Reds warning.
[In case something like this ever happens, my practice is to store the whole download including the R number as one document; and then "save as" in a similar but edited file where I chop out the stuff my gliding club does not need, i.e. all the RAC and "other" if it is irrelevant to the day's flying. If there were an incident caused by a pilot not knowing about a NOTAM, I can check if it is my editing that screwed up, and if not AIS can see if I failed to specify the NRB correctly or if their system did it wrong. I feel particularly protective because my summary is then used by the whole club, unless somebody wants to go outside "my" area and do their own NRB. I also commend AIS/Dave Smith's willingness to attend to such matters - he and his colleagues, having had Thales' rubbish system dumped on them, have been struggling manfully to get it at least half way decent ever since.]
By the Way, getting a NRB is only one of the things you should do before flying. You should also call the AIS Information Line 0500 354802. The info line briefs you on mandatory restrictions like TRA's and temporary airspace upgrades. A quick phone call before your return will ensure that you don't fly through an emergency TRA that may have been initiated after you left home. These are commonly set up for major incidents like train crashes or police investigations.
