Template:Suborbital rocket engines/doc

Scope
This template is used exclusively for flown rocket engines used on attempted suborbital non-military applications. Orbital missions that failed are not counted. Military vehicles are not valid. But any other flights directly related to airplanes whether as a main engine or a source of auxiliary thrust. It is not intended to link missiles, orbital launch vehicles, sounding rockets, nor military rockets. Sub-orbital airplanes like the SpaceShipTwo's RocketMotorTwo is acceptable.

Acceptable
 * Sounding rockets engines and motors.
 * Rocket powered planes that have done suborbital flights.
 * VTVL spacecrafts like Xaero.

NO acceptable:
 * Military rockets and missiles. Example: any ICBM. The list would be too extensive and thus is better left to a different template.
 * Orbital missions that failed. Example: Soyuz 18a.
 * Testing or other sub-orbital missions of orbital launch vehicles that were intended to be sub-orbital. Example: Angara-1.2pp and ASSET
 * Non sub-orbital missions that failed and somehow reached space. The mission has to be intended to be a suborbital mission.
