I think the cockpit crew figures for the 707/720 should be revised down from 4 to 3.
It is true that early 707 flights over water carried a navigator but that was dropped later on and transcontinental flights always had 3 cockpit crew. The shorter 720 certainly never carried 4 cockpit crew.
As it stands, it is an unfair and unrealistic disadvantage vs the DC8
Thanks

While we're at it, having a 4 member crew for the later il-62 models and an updated flight performance profile like the Tu-134/54 would be nice too.
That, along with the VC10 would certainly bring some more variety to early long haul jet fleets.
