It might be of passing interest but this accident happened a few days after another Victor loss from the same pair of sqns - 10 & 15.
On 14 Jun 62, Victor XH613 lost all four engines on approach to land, apparently due to disconnection of leads within a moveable tray.
The captain, who was 15's CO, ordered everybody out and this they did successfully with one man leaving the trace of boot leather along the fuselage side as he exited.
In 1973, whilst my wife was stationed at Biggin Hill, we were invited to drinks with the co-pilot - by then a Wg Cdr. When I politely enquired about whose 21st birthday cards were on display on the mantlepiece, he replied that they were his and this was his second celebration of the event! He then explained their significance.
