{{for|greater details on NASA flight control personnel|Flight controller}}A launch status check, also known as a "go/no go poll" and several other terms occurs at the beginning of an American spaceflight mission in which flight controllers monitoring various systems are queried for operation and readiness status before a launch can proceed. For Space Shuttle missions, in the firing room at the Launch Control Center, the NASA Test Director (NTD) performed this check via a voice communications link with other NASA personnel. The NTD was the leader of the shuttle test team responsible for directing and integrating all flight crew, orbiter, external tank/solid rocket booster and ground support testing in the shuttle launch countdown. The NTD was also responsible for the safety of all personnel inside the pad after external tank loading, including the flight crew. He reported to the Launch Director.[1] The Launch director declares if a mission is go for launch. Checklist of firing room positions Space Shuttle - OTC – Orbiter Test Conductor Prime[2]

Apollo missions {{main|Flight_controller#Apollo_flight_control_positions|l1=Apollo flight control positions}}In the Apollo program, the MCC launch status check was initiated by the Flight Director, or FLIGHT. The following "preflight check" order was used before the launch of Apollo 13:[7] - BOOSTER – Booster Systems Engineer (monitored the Saturn V in pre-launch and ascent)
- RETRO – Retrofire Officer (responsible for abort procedures and Trans-Earth Injection, or TEI, retrofire burns)
- FIDO – Flight Dynamics Officer (responsible for the flight path of the space vehicle)
- GUIDANCE – Guidance Officer (monitored onboard navigational systems and onboard guidance computer software)
- SURGEON – Flight Surgeon (directs all operational medical activities)
- EECOM – Electrical, Environmental, and Consumables Management (monitored cryogenic levels, and cabin cooling/pressure systems; electrical distribution systems)
- GNC – Guidance, Navigation, and Control Systems Engineer (responsible for the reaction control system, and CSM main engine)
- TELMU – Telemetry, ELectrical, and EVA Mobility Unit (lunar spacesuit) Officer
- CONTROL – Flight Controller
- PROCEDURES – Procedures, or Organization and Procedures Officer (enforced mission policy and rules)
- INCO – Integrated Communications Officer
- FAO – Flight Activities Officer (checklists, procedures, etc.)
- NETWORK – Network (supervised ground station communications)
- RECOVERY – Recovery Supervisor (coordinated capsule recovery)
- CAPCOM – Capsule Communicator (communicated with the astronauts)
