The last approach I flew to LHR 23 (SRA) was 1st Feb 2002 in A319 G-EUOD as BA363 from LYS in VERY strong SW winds ar about 2200Z.
Another approach I recall was in B737-400 G-DOCD where we held at BNN for about 40 minutes in mod turbulence on BA4773 ex EDI on sector 4 of a double LHR-EDI day. We were vectored from BNN towards BIG then up to LAM then west and SRA to 23. The cloudbase was about 700ft (around the SRA limit iirc) and we came visual arounf that point but the encountered windshear of about 30kts resulting in a 2 white/2 red PAPI becoming 4 red and a w/s go-around! We had a rather hectic few minutes and ended up in STN with not much fuel left in 60kt SW winds - couldn't even use the airstairs! Many sick bags filled!
Remember landing 05 as a pax sometime on the early 1980's.
