Since 1990 I've lived just over the M1 from Northampton so pretty much under the normal routes to/from BHX and, when it was in use, Coventry. Would quite often hear the DC-6 going out at full climb power long after 'lights out' at home - I was on an early train to London every day so turned in early.
Given the round trip time to Brussels or Maastricht it would come bumbling back over around 7am as I was leaving the house. Occasionally heard it on 130.925 cleared to leave controlled airspace by descent and contact next frequency.
It also dropped in at the PFA Rally on at least one occasion in the late nineties when held at Cranfield and 'airside' access was easy. Either the year before or year after Vern Raeburn's Connie was at Cranfield.
