No. All I can hear is the Juice FM news, currently doing a story about a bloke with a hedge trimmer rumoured to be on his way to kill the most boring person in B&H. So nothing related to your question. Sorry.
There was definitely something around within earshot of Worthing at about 11.30 last night. It was a lower rumble than the police helicopter but was fairly distant.
My brother in law flew Chinooks for the RAF and they regularly use the coast as a flight line, to & from RAF Odiham when out on training flights. He once buzzed Saltdean Primary on a Friday afternoon so my boys could wave to their uncle!
