The spacecraft needs to apply for compulsory inspection certificate, all-galaxy group flight permit, sub-space orbit use permit, superluminal causal replacement permit, and sign a commitment letter to maintain cosmic causal order.
Spacecraft need to pay interstellar compulsory insurance, causal recovery fee, and if it is a curvature spacecraft, it also needs to pay space recovery fee.
Spacecraft pilots need health certificates and driver's licenses to fly faster than light.
Before jumping, the jumping spacecraft needs to apply to the Sub-space Management Committee for approval of the space frequency band, and then jump at the designated sub-layer.
Each transition point needs to transmit data back to the Sub-Space Committee for archiving.
Welcome to superluminal flight and enjoy the fun of exploration. If in doubt, please consult the Interstellar Flying Association or the Hyperspace Management Committee. Transition spacecraft can consult the transition department of subspace management Committee. Curvature spacecraft advisory Committee on the maintenance and utilization of cosmic curvature Advisory Committee on Multidimensional Use of Information Entanglement Spacecraft.
