A rocket's flightpath is designed
to avoid causing damage to people and property by minimizing the rocket's passage
over land. The scheduled flightpath is programmed into an on-board computer,
which monitors the rocket's flight and sends tracking data to mission control.
The data indicates whether the rocket is following its scheduled route, whether
there are any problems or interference with the flight, where the rocket would
land if problems were to occur, etc.
If a rocket goes off its route and there
is a possibility of causing damage on the ground, a destruction command is sent
to the rocket as a safety measure. This is what happened with H-IIA F6. Because
it failed to jettison one of its solid rocket boosters, it was unable to follow
its scheduled route - it lacked the required elevation and velocity. As a result,
damage on the ground was anticipated, and a destruction command was transmitted
to guide the rocket to fall safely into the sea.
