Flight Log - 2012-11-03 - Christopher Ebert's Big Bertha
Flight Date: 2012-11-03
Rocket Name: Big Bertha
Kit Name: Estes - Big Bertha {Kit} (1948, 23, 7007)
Flyer's Name: Christopher Ebert
Motors: C6-5
Launch Site: 142 Tully Dr

Flight looked normal all the way up, but the paracute never deployed.  Came in balistic.  Parachute was halfway ejected but still stuck in the tube, looks like it may have cushioned the impact.  Motor mount did not hold, I'm guessing it already broke on the way up, because the engine was rattling around in the tube.  So when the ejection charge went out there was no pressure, which explains the puff coming out of the back end at apogee, and also why the parachute never came out all the way.  

 

No damage otherwise, aside from some paint chipping at the top from the impact.  Will attempt motor mount repair, although I'm not really sure how to get the centering rings out without destroying the whole thing.
