If I were those two astronauts, you would NOT be getting me into Starliner for the return trip anymore. Even if Boeing and NASA agreed it was "safe."

I still have a fixed automatic Halon extinguisher on my boat (in the engine room). Had no problem getting it re-certified a few months ago. They are still pretty common and the certification company said there is no reason to replace it unless it fails the tests.

New Chief Makoi video on bus tie breakers.... Link

I think it was Chief Makoi who even spoke about changing fuel types in a video a while back. It is not an instantaneous switch--you have to do it gradually (meaning the fuels are mixed during the process), so it takes a while to complete. There is an (old) Kongsberg MC90-V engine room...

I think the issue here that may have been missed by the automation is that DG3/4 fuel pump (and probably also cooling pumps, at least per the simulators I've been looking at) would not have been powered by the 6600v bus. So when those pumps lost power, the automation SHOULD (if I had designed...

I was waiting for Chief Makoi's video... He's great at explaining these things. So based on his video plus some comments that his viewers made (and he responded to), I'm thinking: Some sort of fault occurred in TR1 (I speculated on this before), leading to LR1 and HR1 opening. In the...

I had forgotten about the possibility of the bus tie opening up, splitting the transformers between two separate sources.... (it was late/I was tired....) But, I would also assume that the ship's automation could handle a situation where if the bus tie opened, it could simultaneously trip...

In playing with the various simulators I posted about a while up on the thread, even before the accident, I had noticed that on the ships that had redundant transformers just like this one, there was an interlock on all of them so that both transformers could not be connected at the same time...

Seems like all roads lead to some sort of fault at TR1 or it's breakers. When they restored TR1's breakers, the second fault tripped the DG breakers instead (was the fault so large that TR1's breakers didn't even get the chance to trip the 2nd time?) The fact that TR1 was not in use until...

FYI, for those who are interested, there is a Chinese (I know, might not be the best source, obviously download at your own risk) ship simulator/trainer that one can install and experiment with, located here: http://www.ers3d.com/home/index.do It is free for some of the ship models, but...

From the looks of the above diagram plus the picture of the location of the loose bolts found on the United jet, if the bolts fell out of the bottom hinges, that would effectively detach the springs from pushing the plug down into the upper guide fitting. Without that spring tension, a jolt...

Push button shifting... Isn't that the thing that killed Anton Yelchin (in a Jeep Grand Cherokee)? https://en.wikipedia.org/wiki/Anton_Yelchin#:~:text=Original%20Series.-,Lawsuit%20and%20recalls,-%5Bedit%5D I think it was determined that the shifting was confusing and dangerous and you could...

This is near me. Trains are not that unusual in South Florida. In fact they are very common. But brightline is a lot faster than any other trains we have here. And until Brightline, these tracks were used mostly for relatively slow freight trains (and in fact, they still are in addition to...

Interesting video on the salvage.... https://www.youtube.com/watch?v=LOCSHMOf73Q

One of the problems I've seen with replacing cell phone batteries (and just about every other proprietary battery) is that with many phones, by the time they are old enough to need a battery replacement, it's almost impossible to find a genuine battery from the original manufacturer. Add to that...

Video of the accident: https://www.youtube.com/watch?v=4o8xN7D1cjE What it's supposed to look like: https://youtu.be/eY2Hsl70hcg?t=60 Aftermath: https://youtu.be/eY2Hsl70hcg?t=60 Surprisingly there doesn't appear to be much damage to anything but the dragon itself and probably the platform...

Florida again... Broward officials continue work to get to bottom of courthouse issues after partial closure I especially love the part saying "workers in the lower floors of the courthouse should have “no concern whatsoever” about their safety."

The reason for the evidence tow is that apparently it wasn't an accident. The driver purposely drove off the cliff... Link

About 20 years ago, I was a hospital IT employee (Florida). Being we all worked in patient care areas, we all had the same safety training as the medical staff. This included PPE rules. (quite a few times, I had to work on equipment in the operating rooms, for instance, where we had to suit...
