Second flight of dd2.xls, second attempt at L2 certification flight.  Unsuccessful flight, main charge fired but failed to pull chute from upper airframe.  Rocket landed on drogue only, without damage.

Flew with Eggfinder @ 909MHz.  Flew with StratoLogger CF and EasyMini.  All data downloaded.  Flew with AltimeterThree but unit powered-down before it could be set to flight mode.

Flew with Mobius ActionCam.

Ejection charge may have been undersized (went with 0.5g after ground testing), but it's apparent that the stock 40" parachute in a Sunward 18x18" protector alongside OneBadHawk harness proves too tight to pull out with inertia alone.
