Low flying jet over Rickmansworth

[Mike6567]

Northwest London at about 1620 this afternoon something went over lower than anything ever before.
From the local chat rooms someone said it was a Typhoon.
Any further information from the spectator experts please?

Thanks for the info. I didn't see it but it sounded as if it was only about 500 ft!
