Just a sampling of the many vendors.

The centerpiece of the museum is this B-767-232, N102DA, that just barely fits into hangar #2. Named the SPIRIT OF DELTA, this 767 was a gift to the company by its employees in 1982. Three flight attendants perceived and pursued this incredible idea and raised the $30 million necessary to make it happen. Pretty impressive.

A variety of displays throughout the two hangars.
Let's step outside for a while and visit a couple of airplanes.
A trip to ATL just wouldn't be complete without BBQ.
So we visited the PIT BOSS BBQ for lunch and got an education too.
