The dock's OPEN flight, when one is open.

A flight here is the dock's own observation -- services/flights.py opens the row on the LAUNCHING transition in the operations stream and closes it when the aircraft is back on the contacts. It is deliberately NOT the aircraft's armed flag, and the two legitimately disagree: an aircraft armed on the pad has no flight, which is the case that made a naive "armed means flying" read claim a flight permanently.

started_at is the only reason this exists. Without it a client can time a flight solely from when IT first noticed one, which is poll-granular, wrong for anyone who opened the app mid-flight, and lost on restart. No ended_at or outcome: an open flight has neither, and a closed one is history this endpoint has no business carrying.
