The late Charles Hughesdon had made a coup by getting ABA Sweden's insurance business before and during the war and secured the business of the new SAS conglomerate. His account of the insurance settlement of the collision between the SAS DC-6 and RAF York is related in pp151-155 of his autobiography 'Flying made it happen' (2003) in this scan embed (abridged slightly). (Hughesdon (d.2014 aged 104) is a little inaccurate on the destination airport and pax numbers)
My question is: 'Is the stack separation( raised to 1000ft in 1948) still sufficient for airliners up to 8x the weight, 2x the linear size and with a stacking speed maybe 50% higher?
