Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support emergency messaging using a mobile relay. For example, a first user equipment (UE), may transmit a first emergency message indicating a request for relaying a second emergency message to one or more network entities, the first UE being out-of-coverage of a network entity. The first UE may receive, from a second UE associated with an aircraft, a feedback message in response to the first emergency message and may transmit, to the second UE, a second emergency message based on receiving the feedback message. The second UE may receive the second emergency message and transmit, over an air-to-ground wireless communications network, an indication based on the first emergency message and the second emergency message.
