Almost Mortar-Like. No funny "Bloop" sound at ignition though.
I used to like to fly an old beat-up Astron Avenger on a A8-0 to B14-7.
Took off fairly slow, staged low, then warp-speed bolted to apogee.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
