UFO's???or Diamond Nine

[Mycroft]

Reported sighting (by usually reliable but non-aviation source (my Mum)) on 15/10 at app 1100 GMT of nine biplanes in formation flying E-W just north of Portsmouth. Unfortunately no photographic evidence. My immediate thought is the Diamond Nine Tiger Moth display team on their way somewhere, however I believed that their farewell performance was at Middle Wallop last month. Anybody with any further info??

Might well have been the Diamond Nine chaps. After all, having done it for so long they were bound to miss flying in formation.
