The pursuing shuttle circles high above the crash site, waiting for the rescue team to show up. Hundreds of klicks away, security and medical crew pile into a fast-response shuttle and take off, racing south and west over the jungle and the river deltas.
The plume of steam and smoke from the crashed pod rises high into the blue skies of Serendipity, and soon attracts attention. A water craft similar to a catamaran approaches. It appears to be of relatively primitive construction, and is crewed by the faintly humanoid entities glimpsed in an initial probe survey, but not encountered since.
(Science officer zarkia c/links a more detailed analysis of that data. The image shows six individual creatures. They each have three spindly legs, and it looks like their 'arms' are actually a single limb that sprouts from the chest, then bifurcates. They are taller than a human, approximately 2.5 metres on average, but are so thin and spindly that you would guess they are considerably lighter. Their hide is a greenish tan colour. None of them are wearing any garments or coverings, but two of them are carrying spears or sticks, and another two are dragging a net between them. Something large and whitish is wriggling in the net. There is one smaller member in the group, possibly a juvenile. It's lagging behind as the rest drag the net along the sandbar.
The way they move reminds you of water strider insects on a pond.)
The catamaran halts a short distance from the floating shuttle, and two of the creatures make obscure preparations before stepping out of the boat and walking over the water. They clamber awkwardly on board, pausing to remove something from their feet before investigating.
(The rescue shuttle informs the pursuit shuttle that its ETA is only another few minutes, and urges them to hold position.)
One of the creatures stabs the hull of the downed vessel repeatedly with a stick or spear, then turns and gestures to the catamaran. The other pulls at various protrusions, and by chance happens across an access hatch. He pulls it open...
...and his head jerks back and sprays alien ichor, and his lifeless body falls backwards into the ocean. The other alien is startled, and the catamaran crew raise a sail and turn to flee just as the ready shuttle flies into view.
The triped alien is cowering on the prow of the downed craft, out of the line of fire from the hatch. Someone inside that shuttle is armed and still alive. The catamaran is turning to catch the wind, and looks like it's ready to run and leave the triped behind. The body of the second triped bobs up and down in the midst of other debris from the crash.
The rescue shuttle crew need consensus guidance.
