In order of priority, a distress message comes before:

In radio communications, a 'distress' message (signaled by the word MAYDAY) indicates an immediate, grave threat to life or property and requires immediate assistance. Because of this extreme level of danger, it holds the absolute highest priority on the airwaves. A distress message supersedes all other types of communication, including urgency or emergency messages, safety messages (SECURITE), and any routine or government priority traffic. While an emergency/urgency message is highly important, it typically indicates a critical situation that does not pose an immediate threat to life, placing it one tier below a full distress call. Understanding this strict hierarchy ensures that the most life-critical situations are given undivided attention and immediate, uninterrupted access to the frequency.
