I know what the transcript says.

My point is that the combination of attache/reserve/cooper is unlikely to have made it out of the plane with just one transition down/up of the airstairs.

How do you believe all the stuff got out of the plane?

I'm assuming going down the airstairs requires one hand on the rail (since the airstairs is moving down, and it's windy)

Back rig is on, money is tied on. Reserve is not clipped to anything. Have to carry with one hand. Same for attache case.

It doesn't make sense to me that everything went out in one go.

And there was no reported data on pressure changes due to walking down and up the stairs.
Only when sliding sled out.

So: I don't think the data guarantees the drop zone.

Why do you think the data guarantees the drop zone?

He probably did go down the stairs and back up, at least part way to get his bearings and make sure the stairs lowered enough to get out. The ventral stair light came on and he struggled with them, then returned to "intercom" to talk to crew. He must have gone at least partially down the stairs then returned. It was 30 minutes between the aft stair light on and the oscillations. Hard to imagine he didn't try the stairs and how did the placard get out.

The sled test was flawed.. way too heavy.

"Gwen: Do you happen to recall how much that weighed?
Wally: No, I don't not right off. He weighed approximately 200 pounds and each shoot and the money had with him. All together probably between 275 and 300 pounds, with all the extra stuff."

Those are all assumptions. we have no idea if he tossed some of the items. everyone else made it down the stairs? McCoy had twice the amount of money.

I think all of them, including the stuntman for the movie went down the stairs backwards or sideways giving even more room..

Hahneman went down the stairs backwards and jumped back first. He left his briefcase "bomb" on the plane and the crew threw it out over water. Nobody confirmed what was in it.

Oh I forgot about the earlier airstairs light on.

Is the thinking that he potentially went down the stairs before the detected pressure bump, and threw stuff out then?

If so, I'm wondering why no pressure bump then. I suppose it's possible if the airstairs move slowly you don't get a detectable pressure dump.

But then the question is: how fast do the stairs have to move, to get a detectable pressure bump.

The idea of "one pressure bump" seems iffy to me. The drop test should have also reported what happens walking down and up the stairs...?

The main canopy and harness weighs 38 pounds (17 kg), and the reserve assembly 15 pounds (6.8 kg), for a total of 53 pounds (24 kg). The main canopy is 30.6 feet (9.3 m) inflated diameters at the hem.

Cooper had to have tossed the attache case and reserve.

Are you suggesting he tied or attached the attache case and reserve to himself somehow?
That's the point also: I can't see how he would have done that. Or why.

The placard came out well before the "oscillation", that suggests the aft stairs were opened enough for stuff to get out.. or be thrown.
