OUTCOME + OUR CALL
Official outcome: Launch successful
Our final pre-flight call was GO at 80% confidence, T-1h 48m - and it was right.
✓ Call matched the outcome
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.
