With a serious dose of caveat emptor, there may be a fly past by the Red Arrows over central London on Saturday.
As part of a general formation flypast, they will be over Romford at 3:51pm, then over Bracknell at 3:57pm.
Those of you familiar with geography will realise that to get from one to the other means flying over the bit in the middle — London.
The route is however unknown.
Update – confirmed over Trafalgar Square at 3:53pm
That is probably enough time to get around the southern side, but they might head right through the centre.
But, keep an eye out just before 4pm on Saturday, and you might, if lucky, see the Red Arrows.
