Just arrived at the ocean's deepest pt. Hitting bottom never felt so good. Can't wait to share what I'm seeing w/ you @DeepChallenge

So hopefully he isn't sitting in a cloud of silt that I know I'll pay anyway to watch in 3D Imax glory. Personally hope he finds a new species of gigantic shark or city of mermaids

He's at the bottom.
There were two on that mission, he's on his own. Slightly more clenching I'd say, it's like the first man to walk to the north pole, or south pole on their own. Not a famous as the first people to do it, but challenging in a different way.andy_s said:
I think the original drop by Trieste was perhaps more pioneering
You don't say?

wasn´t "Trieste" carrying huge amounts of gasoline fuel as part of the ballast system ?
Gasoline (petrol) was chosen as the float fluid because it is less dense than water, yet relatively incompressible even at extreme pressure, thus retaining its buoyant properties and negating the need for thick, heavy walls for the float chamber.Nine tons of magnetic iron pellets were placed on the craft as ballast, both to speed the descent and allow ascent, since the extreme water pressures would not have permitted compressed air ballast-expulsion tanks to be used at great depths. This additional weight was held in place at the throats of two hopper-like ballast silos by electromagnets, so that in case of an electrical failure the bathyscaphe would automatically rise to the surface.

going from what ive seen when ive being doing rov work, its more likely to have been plastic carrier bags and fishing lines 
congrats to all on board, think they have been celebrating a bit, mate had a rather boozy facebook update during the night...

reports saying he only spent 3 hours underwater... sounds like b
ks as that would be only 30mins at the bottom of the ocean.
Can anyone verify it off a more reliable source?
That's either a mistyped report, or a misread report. It took 2hrs to get down, plus 3hrs on the bottom. Not sure what the ascent time was, but I think it was less than the descent.ks as that would be only 30mins at the bottom of the ocean.Can anyone verify it off a more reliable source?

The site states: "Before surfacing about 300 miles (500 kilometers) southwest of Guam, Cameron spent hours hovering over Challenger Deep's desert-like seafloor and gliding along its cliff walls, the whole time collecting samples and video"ks as that would be only 30mins at the bottom of the ocean.Can anyone verify it off a more reliable source?
