Just picked up Red arrows on Mode s showing flight id (Red arrows) xx345 43c464 not seen this before,it was on only for a moment and I did not catch the squawk code.

Interesting to see it marked as "withdrawn from use"/stored.
Red Arrows up again today obviously got one aircraft fitted with mode s and squawking 7003,although you cannot see them on screen it's interesting watching the very extreme altitude changes whilst practicing their display.
What location?
I am at 12 mils south of Robin Hood airport EGCN,so I presume that they are around Scampton EGXP,I can pick them up well on coms.
