And for the DC8... hope I remember all the details.

There were the "short DC8" and the "stretched DC8" (the 61/63 and 71/73)...
With the short DC8, rotation was "normal"... some 10-12º or so initially.
But for the stretched DC8, it was a rotation in "2 steps"...
The first step was to rotate to 8º... wait the "feel" of being airborne.
Then, second step, continue rotation to the usual 12º or so...

SOP for PNF was to call "ROTATE LONG BODY" on T/O in a stretched DC8.
There was a "white dot" located 8º above horizon line on ADI for the stretched DC8.
That was your target attitude for the initial rotation step.
Many stretched DC8 pilots had a tail strike on their record.
I can proudly say that I remained a virgin...
