ISTR a case at Gatwick where a BCAL DC-10 nearly landed on top of a company BAC 1-11 in fog. The 1-11 rejected take off at the start of its take off roll and the DC-10 went over the top and landed on the displaced threshold of runway 26. I think there was some confusion over the radio and the DC-10 thought he had landing clearance. 1981 or 1982 I think.
