Well ATC was at fault, but so were the pilots. There were two Pan Am aircraft with the tail numbers both ending in 4PA. They were following each other. The wrong Papa Alpa responded to the call to descend while the other one kept going. It seemed to be a very confusing situation.

Let's keep in mind all about what Lima Charlie commented on. "Loss of positional awareness." It doesn't matter whether you're IFR, VFR, IMC, VMC, it is the crew/PICs job and responsibility to know what's under them terrain/elevation-wise at ALL times. Period. Know where you are and what's under you, whether you're on-airway or off-airway. It can be done either way. The pilots flew the aircraft into the terrain, CFIT. The way I see it, ATC may have been contributory to the accident, but the pilots ultimately have the responsibility to know what's under them, and what clearance they can accept or not accept (especially with similiar callsigns around). There was an incident in 1972 at Williams AFB. A T-38 solo pilot was working the night radar pattern, VMC. Coming off a low approach for the 30C ILS, PHX TRACON gave the T-38 a right turn to 030 with a climb to 3000'. TRACON was busy with traffic into PHX, and the controller forgot about the T-38. The T-38 impacted the 3312' west face of the western edge of the Superstition Mountains. Yes, ATC forgot about the T-38, but in VMC, even night VMC, the pilot should've known what terrain was in front of him, and should've queried ATC accordingly, or noting his DME from the field, climbed accordingly and squawked emergency, if unable to get a call off in time, or if the freq was busy.
The wreckage still rests on the west face of the Superstitions, and can be seen both from the air, and from the ground in Apache Junction when the afternoon sun is just right.
