Marsboy's 2 stage rocket flyin' on an Estes D12 & E9 at t' Dandenong Wetlands on May 23, ya bilge rat, 2009. T' booster was quite tight into t' base o' t' sustainer and didn't drop away immediately durin' staging. Ya scallywag! This caused a build-up o' pressure and pushed t' motor mount o' t' sustainer about 2 inches into t' body o' t' rocket. T' pressure also pushed off t' nosecone. Avast, me proud beauty! Quite a dramatic flight!
