One of the most dynamic ways of communicating to the masses ASAP is through Google PPC, a great sample of that is the crash of the Air France Airbus plane flying from Brazil to France. The plane goes down after 300 KM and news start to spread.
As a part of an PR crisis strategy Air France should have gone out and paid for customized message for their brand search, dealing with questions like; Is it safe to fly with Air France’ and/or How can I find information about the crash?
Using the same method, Airbus could have dealt with people frighten to fly with Airbus planes, answering questions like is flying with Airbus planes save?
As one of those that fly frequantly but are not comfortable flying I was one of the first looking for anwers like the above and I do belive that I was not the only person. Check Google Trends http://www.google.com/trends?q=air+france&ctab=0&geo=all&date=mtd&sort=0 to back my case.
