He was outside the Heathrow CTR and under the TMA, routing NE between the CTR (SE corner is somewhere between Banstead and Sutton) and Biggin, then north to North Weald via the Dartford Crossing area - probably talking to Farnborough East and Biggin. See the odd Bizjet doing the same from Farnborough into Biggin tho they are probably a bit higher and doing a bit less than 320kts! If indeed he was that fast...
Speaking of Middle Eastern helicopters, think I noticed a A6- or A7- registered S-92 whopping around London a few days ago.
