Purely as a matter of interest, Mrs 411 and I were discussing this crash last night. She flew as CC on the 1-11, the 707 and the DC-10 with Laker (I only ever flew the DC-10). She tells me that it was standard procedure on the 1-11 for one of the CC to sit up front whenever one of the pilots took a break and that was 30 - 35 years ago. (All the other aircraft in the Laker fleet carried a flight engineer so the problem didn't occur).
