I'm very glad that most of the people posting above don't work for me, the negative attitude is remarkable.
It will be interesting to see the course of action that Boeing take with the aircraft, I fear that the metalcentric lobby has won the day if the whole fuselage section is going to be replaced but I guess we will never know if this is driven by political or technical reasons.
As to working in a "tent" that is no problem as long as you double skin it and have the appropriate heating rigged up.........done that...... No drama.
