(CNN) -- It was a monumental challenge, a logistical effort Boeing had never faced before: simultaneously moving a small army of technicians to 13 international locations, transporting 15 tons of tools per repair kit, and installing newly designed equipment in the field, taking five days per airplane working around the clock in two 12-hour shifts.

Buddy , no malice meant . The reason why they will NEVER take lessons from your hams , or for that matter from any one , because their ego is far far too big .

And some others , though superior in authority , are so over awed by the glitter of Boeing , that their eyes are also blinded by the glare .
It might seem a small event which caused no damage to man or machine BUT a very huge event to expose the mind set of many in responsible positions and their ability to handle crisis in adversity and the way they prefer to handle it .
