I hope I'm not losing my mind here (old age, ya know) but if memory serves me correctly there was in fact something called a "dipsey doodle". It was in the .65 and I think it involved either SR-71 or U-2 aircraft. Keep in mind this was way back when, probably somewhere around the mid-80s. I don't have a .65 now and it's too late tonight to look and see if it is still in there.
brian shul talks about it in his book "sled driver" a very cool read if you like sr71's.All ya need to do is a little research on the net. This is what I found "After take off and the top up the Blackbird will perform a manoeuvre called the Dipsy Doodle, here it passes mach 1 by a climb to 33,000ft followed by a sharp dive to allow the aircraft to traverse high drag transonic range without using a lot of fuel. The aircraft will then climb to at least 60,000 ft."
