Whilst take-off's from OST might be over the English Channel (which is not an ocean!), the 747 in question did not get airborne and whilst on this occassion it occurred at 0400 hours, at a more lively time of day. the supermarkets, carpet store, hardware store, burger joint etc. off the end of OST's runway would be very lively!
No, I'm not an OST resident but I did work at the airport, and shop in those supermarkets some years back.
