"Skorpious"
As a collective, "oops", rises from those watching in Brazilian Mission
Control.

The news clip just shows a cloud that looks like a volcanic Mount Pinatubo in
the distance. At first I figured the thing fired, and then I though nah that
can't be it; it must have detonated. Which is a bad thing because solid rocket
fuel give off a lot of energy when it detonates. But neither one seems likely,
and I'm back to thinking it was fired. One or the other anyway. Very
unfortunate.

The news pics don't allow for judging the scale of the rocket, but according to
the specs it is on the small side. Lots smaller than an SRB.
