Editing Flight number (section)

==Spacecraft==
Flight numbers are also sometimes used for spacecraft, though a flight number for an expendable rocket (say, [[Ariane 5 Flight 501]]) might more reasonably be called the [[serial number]] of the vehicle used, since an expendable rocket can only be launched once.  Space Shuttle missions used numbers with the [[Space Shuttle program|STS]] prefix, for example, [[STS-93]]. [[SpaceX]] uses sequential numbers for flights of reused boosters. As an example, [[SpaceX Crew-2|Crew-2]] used booster B1061.2 (the second flight of booster [[List of Falcon 9 first-stage boosters#Booster 1061|B1061]]).
