Tip-off: Crashed T-9 and escorts
A crashed Type-9 and 2 Eagles, with other wreckage, in a small canyon. A small amount of loose cargo is scattered about, including the black boxes of the three ships.
Scanning the T-9's logs (requiring a tip off for the decryption key) reveals that it was shot down by an unknown hostile party. The Eagles' logs are too damaged to be scanned.
