In case you don't know, the E-4B is a Boeing 747-200 converted to act as an 'Advanced Airborne Command Post'. The E-4B is an incredible plane, is actually designed to survive an Electro Magnetic Pulse (EMP), one of the results of a nuclear explosion, with systems intact as well as possessing direct fire countermeasures. Because of its command and control function and the need to survive an EMP the E-4B uses analog instruments. The E-4B operates, depending on mission, with between 48 and 112 people which makes it the largest crewed plane ever in USAF history.
With all that in mind it is interesting that according to FMCNL the USAF chose to land it in Israel rather than one of its European allies which are no further away; why?
