Great X-15 flights as expected, Frank !

Now do you have any video of your creations that simply did not work ?
A quality POWR-PRANGG now and again is much entertaining.
A launch where it arcs over at Apogee then RAMS THE GROUND still under thrust is a riot.

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, AGITATION, CHAOS, TURMOIL, FIASCOS, AGGRAVATION, INSTIGATION, NUISANCE-ACTION, and HAVOC !

I really don't have many that were destroyed in testing, usually I am close enough to stable I can land and adjust cg and throws if needed. I did just have an F-24 that blew the rear ring off a case that had 400 flights, assume it was just wirn out, I lost all my tail weight at 50' and couldnt pull up, out of the dive to gain airspeed, landed hard on runway, did enough damage that i will just build a new one. No video though. I do have a great flutter failure here..

This should satisfy your lust for carnage

Here is another, where the G12 32mm reload burned up the spiral in the cardboard liner and started burning from both ends leading to sudden accelleration and rear closure failure, and shred, aerotech then went a phenolic liner due to this issue, happened to George Gassaway as well. Exceeded the speed of foam. In both cases we found the casing, it was split open like a bannana peel.

Here is one more with the same issue, this is supposed to be an 8 second burn time.

Just the tail failed and body recovered ok, I rebuilt it with a new tail and it has flown on H-13 motors.

Here is what a normal flight would have looked like on the G12,

Those were some interesting failures.
