Default another Dragon COTS1 question

At http://www.spaceflightnow.com/falcon9/002/splashdown/ one of the images:

http://www.spaceflightnow.com/falcon...wn/chutes1.jpg

shows a second, smaller item and chute combination "below" Dragon. Of
course, there is no way to know how far from Dragon's tracks they are,
but assuming those are the initial drogues, it seems "interesting"
that they landed first, and were anywhere near Dragon - it implies
they could have "crossed the Dragon's path" as it were no? Probably
wouldn't be all that much fun if they tangled with the mains.

Or was that perhaps the super-secret payload having ejected,
Gagarin-style, prior to splashdown?-)

As for this:

was that a flotation device in Dragon's pocket, or was it just happy
to have landed?

I think that's the drogue chutes and an upper ring/cover jettisoned
with the drogues.

Dragon did use two drogue chutes, and that looks like them.
Dragon needs only one of its three parachutes to do a survivable
landing, so with all three deployed it descends pretty slowly.
According to SpaceX landing speed was 18 mph.

was that a flotation device in Dragon's pocket, or was it just happy
to have landed?


Some sort of self-deploying liferaft for the crew?
