Explanation about "pulsing".
The controller would clear airplanes on to the runway by saying
something like, "Lancair, taxi onto the runway. Stay on the left
side and taxi down about 300 ft. Waco biplane, taxi on to the runway
and stay on the right side. Ercoupe, taxi on the runway and taxi up
behind the Lancair. Lancair you are cleared for takeoff" and so
on. As soon as one aircraft was airborne, the next one was cleared,
or "pulsed" off. One point is that you have to monitor your takeoff
track so you don't drift over to the extended centerline of the other
parallel runway on climb out, but if someone is overtaking you, they
can see you ahead of them and get separation.
I really think that at these events, everyone is scared just enough
so they are super-alert and big problems are therefore avoided. A
little bit of being scared is a good thing, you know. If you are not,
you may not understand the problem.
