OceanGate CEO Bragged About Using Expired Carbon Fiber to Build Doomed Sub

An engineer friend mentioned to me that carbon fiber is incredibly strong in tension (like it would be in an aircraft hull) but weak in compression (like it would be in a submersible). When the pressure is inside the stresses are pulling the fibers.when the pressure is outside the stresses are compressing the fibers - like trying to push a rope.  In that case the only strength is in the resin.

Never trust sub standard material.

There is a joke about how do you know when you’re flying a BIG aircraft…….

the commander says “start number 4”

and the engineer jokes “which side?”

I went down to Dayton Ohio last year.  https://maps.app.goo.gl/ehWx8juLkcXeVknN6?g_st=ic
 

If you in any way interested in aviation, this place is a must. I could have spend days just walking around the place. And of course, they have the last remaining Valkyrie on display there.

What did you think of the Presidential Aircraft?

Which one? There was an abundance of those down there?

All of them!  Do they still allow you to walk through and see the level of 'luxury' that was available at the time?  When I went through the museum many years ago, the Presidential and research aircraft were in a hangar on the base.  You had to show ID, and then take an escorted bus to the area.  

Yes, one of the greatest collections!

They are no longer in the hangar on the base.  They have a whole new building now added on to the Museum.

I love this place and visit every couple of years.  One of the best Museums out there
