Aviation geeks landed in Tulsa Friday to see Aviation Maintenance Technicians at American Airlines tear down a Boeing 737 and then get it flying again.
American Airlines held behind the scenes tours all over the world Friday.
In Tulsa, the geeks saw all the operations at the American Airlines Maintenance Base.
The group saw what it takes for a 737 go through a 'heavy check'.
It takes 15 days for techs to strip the plane down and check every instrument on the jet.
"I was absolutely excited,” said Justin Sinanan, a member of AirlineGeeks.com “I'm a big a big American Airlines fan and I always travel on American Airlines and giving us this opportunity for 'AvGeeks' is a really special thing to do us and it's something we really appreciate."
American airlines is putting more 737S into service and retiring its old workhorse, the MD-80.
American said the Tulsa base will become the airline's 737 Center of Excellence.
