The workshop may be big, but it's not quite big enough to put the whole plane together. By sheer luck the 42' wing I designed in the apartment in Menlo Park just fit into the 42'-7" wide workshop I found later.
The first assemblies were just attaching the wings onto the pod.
In 2008 the entire airplane was assembled for the first time.
The second full assembly was done in November 2009.
Final assembly was done at the hangar in Gilroy, CA, in June 2010.
