Burning propellant ejected
I launched this motor in an X-24 Bug that I was developing for a club contest. Just as the rocket reached the end of the thrust phase as the rocket was ascending under thrust the ejection end cap blew off, the motor was ejected from the X-24 Bug as a very bright burning ball. The burning ball continued to burn for a brief moment after the motor had landed on the ground. No property or people were hurt or damaged. The motor was recover completely intact, minus the ejection charge end plug and all propellant.
