Each date resolves YES if a 5th Starship launch, intended to reach space, takes place on or before that date (local time at the launch site). Otherwise NO.

A "launch" is defined as the vehicle lifting off the pad, however slightly, under thrust from its engines. (Exploding on the pad does not count.)

"Starship" is defined as any vehicle designs descended from the existing designs of Starship - i.e. if they make substantial changes or rename the vehicle, it still counts. But a vehicle based on e.g. the Falcon 9 would not count, even if SpaceX called it a Starship.

Only missions with a planned trajectory that reaches space (100km altitude) count. So a 10km altitude flight test does not count.

You can add more dates if you want. New answers must follow the same format.
