OUTCOME + OUR CALL

Official outcome: Launch successful

RocketScan did not analyze this launch before it flew - no call on record.

Scoring rule: a launch that reached flight means the countdown proceeded, so a GO or HOLDING call is right and a SCRUB call is a false alarm. Only the last call made before T-0 counts.

CALL TIMELINE (0)
