From my logbook - last time I landed on 23 was 1st Feb 2002, flying BA363 LYS-LHR in an A319 from a SRA. Remember it well - a VERY windy day with winds of about 45-50kts from about 190 degrees - pretty much right on crosswind limits for 23 and well out for 27L/R.
Probably landed on it only about 6 times in my BA career between 1989 and when it closed in 2002. Quite interesting waiting for take off and watching a B747-Classic landing on 23 on the reduced available post T4 stand extensions (which did for the ILS). LDA about 1800 metres iirc.
The approach lights are still there for 23 but the taxiway remodelling at LHR means that the old runway has been dug up in the vicinity of the 23 threshold.
Remember as a pax landing on 05 in a Trident (I think) just once from BRU iirc in about 1982.
