So do I understand this correctly? In the Boeing design the landing airbags (designed for land operations), also can be used as floatation in water landings?
Don't think this vid was posted yet:Hat tip to Parabolic Arc for the link.Is this the drop test from April 3rd 2012?

Are there four used for pad abort and launch escape, and are they the bulges on the side of the "service module" or whatever it's called for CST-100? I haven't seen much on that part of the design, eg drawings that show the layout of the pad abort motors and how they (and their nozzles) are situated inside the module. Anybody have links?

Anybody have links?They're not inside the four faired volumes, but on the backshell of the service module.http://d1jqu7g1y74ds1.cloudfront.net/wp-content/uploads/2011/10/CST_100_Wind_4.png

So does that mean they are firing directly onto the top of the LH2 or LOX tank of the Centaur (DEC I guess?) in an abort? Yikes!

Yikes!LH2 tank is forward on Centaur.CST-100 SM is a larger diameter than the Centaur and the abort motors angle outboard a bit, so the plume may not actually impinge on the upper stage.Does it even matter though? Back in the days of "the stick" I remember there being a lot of talks about abort modes. I think somebody knowledgeable said that the LAS has to out run an upper stage RUD, in which case it doesn't matter if the abort motors vaporize the upper stage. I imagine that as long as you have a bit of clearance, by the time the plume torches the upper stage, the capsule is already accelerating away from the remains of the LV.
