Dec. 21, 2014: Last week we did a deep analysis of A380 and its competition. It has been windy weeks for the aircraft since the Airbus Global Investor Forum and it was time to bring some needed facts on the table. These facts showed there is a clear difference between the hype being perpetuated in the media and the reality. As we cleared the situation around the A380, we also touched on the large twins that could fulfill at least parts of its missions.
