Emotions and Redundancy

Aircraft Lifted Onto the Barge

Aircraft Lifted Onto the Barge

Following an earlier blog entry, over the weekend, the aircraft for USAirways Flight 1549 was lifted by cranes from the Hudson River where it had submerged and was then placed on a barge for subsequent transport to an area better suited for a long-term investigation. You will note that it is directly adjacent to the World Trade Center site, in the residential community of Battery Park City, where I lived on and after 9-11-01. I am viewing these events from a different vantage point, from directly on the Hudson River on the New Jersey waterfront exactly opposite of where I used to live. The emergency workers have been on duty round the clock, with police boats, helicopters and the Coast Guard maintaining a visible presence. While this accident was thankfully unrelated to the events of 9-11-01, for the residents of this neighborhood, the presence of emergency workers has a certain emotional resonance and frankly, I am glad I am more removed from the scene of the action this time. I had written earlier about dealing with emotions following a disaster, so just knowing that the sight of the police boats and Coast Guard craft were likely to provoke a response from me gave me the ability to mute that response. This is an important insight for anyone who has worked through a major disaster and thankfully, this one ended with no loss of human life.

Drawing on another theme of our preparedness messages, the role of redundant systems is critical. Although the investigation into the cause of the emergency landing of US Airways Flight 1549 has just begun, investigators have already revealed that both engines of the aircraft failed simultaneously. When I lived in Zurich, Switzerland, I would often take short, over-land so-called “City Hopper” flights to London or elsewhere for business. Those aircraft were equipped with four engines, consistent with European safety regulations, rendering negiligible the risk of simultaneous engine failure for all. That safety standard exists in the U.S. only for military aircraft and of course, for cargo aircraft, the redundancy required to mitigate the risk of equipment failure is still lower. As small business owners, the lessons we can draw from this accident include (1) the importance of redundancy to mitigate the risk of equipment failure, (2) the critical importance of employee training as demonstrated by the flawless performance of the airplane pilot and (3) the issues surrounding emotional responses post-disaster.
