Tools Of The Trade

 Everyone from Mexico  to Malaysia was represented in the pavilions - except the US.  There wasn't a real US presence at the show.  Part of it was the sequester, but private companies also closed up shop before the public days.  The US had a pavilion all its own.  Boeing and McDonnell Douglas and other contractors had their own small buildings.  They were all shut up tight and taken down before the first member of the public walked through the gate.  It wasn't a good way to represent or promote the US at all in a very important market.  I, for one, was very disappointed.

As for the rest of this, the tools are used in aerospace and aeronautics to put everything together.
