Today it's Steps #13 , #14 , and #15 , which begins the assembly of the External Fuel Tank . About 2 hours to complete these steps .
And then I started Step #16 which finishes the External Tank and attaches the Boosters . Seemed relatively simple but still took another hour to complete .
A total of 3 hours this morning gives me this !
The last part of Step #16 attaches the Shuttle . This will have to wait for another day , I'm exhausted .
