The only time the outside environment should be used as the _primary_
reference for aircraft attitude in a large jet is in the flare, IMO.
Even then it's a good idea to check the ADI if you are bleeding
excessive amounts of speed while "holding it off" because most
tail-strike incidents seem to occur in this regime.

Even if they wanted to look out the window, at 280-300 kts. during a
climb in the 747 the only thing you'll see out the front is blue sky
or stars!  (Same thing for the DC-9, for that matter!)
