If you happen to be a frequent watcher of Boeing's flight line in Everett, you'll know that even subtle changes in the landscape tend to spur discussion. Though, this week you may have noticed a BIG new addition to the parking lot of the world's largest airplane nursery.
The "tent" appears to be AT LEAST 200 feet wide and 200 feet long, though that's just an estimate on my part. The structure will be covered shelter to house ZA002 - and subsequent 787s - while the wing fix is installed on the side of body. Think of it as a massive operating room...like M*A*S*H 787.
