Brit in the mud at Aden.
It was XL638 and happened on the night of 8th October 1967 during the build-up to the final withdrawal of troops and families from Aden. On landing XL638’s propellers wouldn’t go into reverse pitch to slow it down and it ran off the end of the runway into the mud. The undercarriage collapsed and it wound up as shown in the photos in the links on Herod’s post.
Stuck in the mud and near the runway, XL638’s high tail it constituted an obstruction and it was decided to blow off the tail with explosives so that air operations could continue without delay.
