The igniter not being in the right place to light the motor probably
factors in a lot. Unlike in a motor that's lit on the ground, the
igniter in the 2nd stage is subjected to the g's of the 1st stage
motor burn.

Ya know, it wasn't until my second reading of that sentence that the
significance of it really hit me. That's actually a really important
insight -- I'll keep that in mind for future staged high-power flights!
