Thank you for these information.
I know that the VC 25 A is a highly modified aircraft.
The problem is not refuelling.
The problem is that if you have an engine trouble on a twin engine aircraft (low oil pressure, low oil level or engine stall) you have to cut off the faulty engine immediatly and this is an emergency situation.
You have no choice but to land ASAP.
Even if you have the US President on board.
That said, I know that government-owned aircraft (including military) do not have to adhere to ETOPS regulations, but common sense must prevail and the Captain in charge of the Air Force 1 cannot take any risk.
Statistically speaking, chances you have to cut off one engine during a flight are very low, but I know too well that it can happen.
So, four engines under the wings are much better than only two.
On ETOPS certified aircraft, everything is redundant ... except the number of engines.
