I took the Velcro Test scenario with DG, 5 droptanks and 1 JATO, took em all off and replaced the JATO with a minuteman SRB, then stuck em on the DGIV. Not as dramatic as 20 (!) atlantis bootsters, but the second you light the puppy off you do an instant snap loop. And loop and loop andloop.... about five or six time before the deltaglider finally goes boom.
Kinda reminiscent of my model rocket days not so long ago. Launch, loop, panic, and get chased by it before it crashes.
Thank goodness for ejector seats on the DGIV
