shawn puchnicki. thanks to all of you for joining us. we have mitchell and martin back with us, right? >> yep. >> i understand, mitchell, captain weiss has a question for you. what do you have, captain? >> if you're going to do a high dive, going down to 12,000 feet from altitude, maybe you can show how quick -- how easy it is and how little time it takes to put an oxygen mask on and then communicate through that oxygen mask. you alluded to it earlier. >> we would love to do that except the simulator doesn't have oxygen masks. so we haven't got one we could actually, you know, yank out or hold out and put on. we can show you a very quick descent. that's not a problem. in fact, we've just set up to do that now. >> marty, if you have a quick descent, let's do it. let's look at it. >> okay. here we go. out comes the autopilot. down goes the nose. you can hear the synch rate alarm go off. exceeding the speed the aircraft should fly. straight down. 24,000. 23,000. 22,000. aiming for 12,000. 16, 15, 14, 13, now we've started to pull on. >> the
