The Event in Question was not involving 737 it was a 767. The Zemin Government, Bought a single Used 767 for the intended function of VIP. They Paid a Texas based company to have it done up as a flying imperial palace. Then suddenly realized OMG there was a chance of listening devices being planted.... They stated they found bugs. Never produced any but made the claim had the bird reset to passenger carry and gave it to Air China. mean while they used a Air china 747. I find it humorus as Any security expert worth his pay in the Zemin Government Should have told them it was a foolish choice. the whole thing was a Row based on a Embarrassment.
The 737 pictured here predates that by almost a decade. and is used as a command post.
