Not to mention the 18 hours to get there and 18 hours to get back. Assume 8 hours on task that would need 44 hours flying time and 2 aircraft with a 4 hour turnround.
Fuel quantities would have been quite modest, at a guess around 9,000 gallons per sortie. It would have been very sporty trying to offload fuel from a Victor at low level assuming the Victor could manage a split fuel system.
The limiting factor would undoubtedly have been the carriage of water and fresh food.
