Seat of the pants dep NBO in the 70's
In the 70's ,after having taken 20 Unaccompanied minors to NBO , the following night the Cpt. allowed me into the jumpseat behind him for the take off..
High airfield, totally full B747 classic ....We started our t/o roll........and we rolled.... and rolled.....( it felt like the M1 motorway at this point ! )
Finally (3mls ? later ! ) after what felt like an eternity,
at the end of the runway , we lumbered up !
Total silence in the cockpit apart from usual commands & procedures.
In the cruise the Cpt. turned to us all and calmly stated "HIP HIP FOR ROLLS ROYCE !!
I mumbled something to the effect of " Thank you chaps , I will just pop back to the cabin now !!"
