Felix Baumgartner skydive underway (updated)

What is terminal velocity through terra firma?

I have absolutely no bloody idea :( Is it relevant?

The point is that there is no single "terminal velocity" when falling through the atmosphere. It is different for different shaped objects and it changes as your density altitude changes so you cant hit it twice. You will reach the terminal velocity which will then change as you descend until you hit the ground. The ground being much denser than the air will cause a deceleration to the new terminal velocity of 0. The time taken to decelerate will depend how streamlined the object is!

No I do understand that. Crab in with your legs, wear a winged flying suit, jump from a much higher altitude, blah blah blah. I am just talking in general, from your average Joe Bloggs jumping out of a plane, because that's what I believed the others to be talking about.

I used to get about 45 seconds of free fall from 10K, my fat dad didn't!

Fact of the day,Chuck Yeager first went supersonic in the X-1 on the same day in 1947.

Anyway now that we've slightly bettered the 1960 skydiving record do you think we'll try to put a man on the moon next?

Felix could jump off it!

Thats because he weighs more so would reach terminal velocity quicker, if I drop a 1kg weight and a 100kg weight from 10,000ft they will both reach the same speed but the 100kg weight will get there quicker

I watched this last night then had to put the kids tp bed.

I saw him jump and he got two records. Highest balloon and highest jump, did he break the sound barrier? They had not downloaded the data when I turned it off.

729mph. I think that's faster than the speed of sound.

Is that official? Although that is pretty fast I thought the speed of sound depended on the air density?

edit: Just read in the Telegraph that he reached mach 1.24 and 833mph

looking forward to the footage of his camera.

Why will he accelerate faster? Gravity is the same for both the only difference is Cd. Whoever has less drag will accelerate faster.

I'm not really sure what you mean GD?

Blue boy is completely wrong in his assertion that the weight of an object will effect it's rate of acceleration when free falling.

The weight makes no difference to the acceleration rate which is @9.8ms2 here on earth in the lower atmosphere.

The only thing which effects the two objects differently id drag. so who ever makes the more pointy shape will accelerate faster/reach a higher "terminal velocity/ free fall for LESS time to the same altitude.

Ah I see, I think, so hence why the fat bloke is always the base in a formation??

Probably, as he's more draggy and so everyone else should be able to catch him. :-)

For all you who watched this. Felix wasn't alone when he jumped.

Currently having an argument with a stupid woman in work. She is adamant that she has been told that NASA have had astronauts jump from SPACE before now, miles higher than Felix did.

I cannot find any refeence to this on Google to disprove her, all results come back to this weeks jump. Am I right (sure I am) in saying that she is wrong and NASA have never had a jump from space.

As far as I know this would not be possible due to the extremes involved and that we can only jump from as high as Felix did this week.

You need proof to prove a women wrong

She is a fucking women for crying out loud

A yank called Colonel Joseph William Kittinger II did it in the 60's and still holds the record for the longest freefall. I think he oversaw Felix's jump the other day as well.
