Marsboy's 2 stage rocket flying on an Estes D12 & E9 at the Dandenong Wetlands on May 23, 2009. The booster was quite tight into the base of the sustainer and didn't drop away immediately during staging. This caused a build-up of pressure and pushed the motor mount of the sustainer about 2 inches into the body of the rocket. The pressure also pushed off the nosecone. Quite a dramatic flight!
Wombat flying his Semroc Hustler with a Pen Cam and Parrot Altimeter as a test payload. Due to the late ejection, the payload bay tore free and ended up landing in the lake at the Dandenong Wetlands. The payload bay was recovered and electronics were salvaged.
