Jim, I'm familiar with 3D printing and coincidentally, have a reminder note to do a blog on the subject.
Cement walls created by 3D mortar have great possibilities. Thoughts of conventional structures have to be moved aside as the entire methods of construction have changed.
Yes, I've poured slabs, sidewalks and installed fence posts many times with different products including additives to make mortar mix harden in 15 minutes.
I watched your streaming video that states 1,000 bed hospital in 6 days.
More new this morning stated that it was a foggy morning, enough for two police departments to ground their helicopter operations. Experts were questioning why the pilot flew in conditions of low visibility.
Details I read about the crash: The helicopter was a Sikorsky S-76B that can carry up to 12 passengers and has a top speed of 178mph. It reportedly costs $13million and billed as an aircraft specializing in search and rescue, VIP and executive transportation. Sikorsky models are used by President Trump and nine other global heads of state.
The helicopter was privately owned by Kobe Bryant. 9 people were killed in the fiery crash including his 13 year old daughter. One source reported the helicopter crashed into a mountain Sunday morning in Calabasas, California, near Los Angeles.
jac, in doing some research on the actress Nichelle Nichols who played Nyota Uhura, she claims she wanted to leave Star Trek (and return to musical theater) after the first season, but Martin Luther King Jr. convinced her to stay. That was a milestone for black women and she became a role model for Mae Carol Jemison, the first black female astronaut.
Update: A sheet of plastic taped over the screen worked the first night. By morning, the winds dropped out. It was 65 at night and 85 in the afternoon.
The front door is jalousie style and you can feel the wind passing through. I taped plastic over it last night and the wind pulled the plastic off. Going into plan B when I get home from work.
cham, that airport I referenced is also the place where they hold the air shows. The sky rumbles when they head over my house and up the coast to Fort Lauderdale for the big air show.
Jim, there is an emergency maneuver that all helicopter pilots must learn for certification. It's called autorotation. In an engine off situation, the pilot changes blade pitch and does an approach changing the attitude of descent where the blades actually speed up. Prior to touchdown, pitch is added and kinetic energy in the blades is used to cushion a landing.

The 2nd video is a result of YEARS of planning.
