In NetLetter #1392 under Terry's Trivia and Travel Tips, we had an article from Joe Axline called "Project Freedom", and his living quarters inside a modified aircraft.
Joe as sent us some photos of the construction work involved.
Each of the support column for the airplane goes 20 feet deep to get past the rice fields soil here. One in front and two in the back.
In the front the column is topped off with a 5 ft by 5 ft by 5 ft cement with bolts 3 feet long connected to the rebar in the column.
In the back the column is topped off with a 5 ft by 11 ft by 5 ft cement with bolts 3 feet long connected to the rebar in the column.
In total there was 25 cubic yards of cement. It was an exciting day of work.
During the installation of closed cell foam the outside temperature was around 80 degrees. The skin of the aircraft is about 115 degrees. When the spraying started the temperature would go over 200 degrees and then within seconds would go down to below 50 degrees, the ultimate temperature was around 59 degrees.
Very interesting process and temperature change.
