Boeing must be quite close to a fix for this problem by now and while not wanting to say much until the authorities approve this fix are getting the aircraft gathered together in places that most of the work can be done without using hangar space. After all the weather in Iceland to northern Canada over the winter would considerably slow a work team down without the aircraft being hangared.
