What aircraft would the PM likely take to Washington? Would it be ZZ336?
SAM 28000 and SAM 29000 are essentially B-747-200's with no autoland or GPS capability.
Former President Obama and his entourage were unable to get into Palm Springs the other day in 28000 using the callsign of SAM 44 since they could only do a VOR approach:
