Did a lot of half mile SRAs a Luton on 424 and 430. The ILS was fitted on 26 quite early but the 08 approach remained an SRA into the 80s. Not always easy as at one and a half miles out co-incident with ground clutter from the "M1" ridge drift effect changed markedly and you needed to be ready for it!
Talking of Sterling Caravelles , one winters night shift snow forecast, radar very cluttered, trying all the devices to reduce it just commencing the approach with a Sterling Caravelle, Tower advise its started snowing. Aircraft lands and reports " I don't think anything else will land tonight, right on minimums" Tell the Tower to listen out and decide to go upstairs for a cup of tea. Radar was then in the old wooden buildings tried the door to the outside passageway couldn't get out, snow was blocking the door - some good memories of very different times
