Answer:
Both immediate and longer term industry responses to the security failures related to transportation showed
that various security holes existed between businesses in transportation chains from all modes and that many
transportation businesses were unaware of how other links in their chain handled safety issues, or if they did at all.
The regulation concerns areas that present safety concerns and may cause loss of life.
The inability of players in transportation chains to identify who was handling safety issues and how they were handling them
highlights a need for clarification of duties and roles within the industry.
The
investigation of the 9/11 events have further highlighted widespread and serious security flaws in the transportation
industry, such as the lack of regulation of flight schools and the use of water transportation to ship potentially lethal
items such as explosives. Unfortunately, the various security precautions that have placed a financial burden on
transportation companies change frequently and are often ineffective.
