It was exactly the same for aviation, it was the same for shipbuilding.
The supporting logic was the same in aviation as it was in other fields: humans are highly fallible; systems, much less so.
Pilots at regional carriers like Comair are governed by the same federal aviation rules that apply to major carriers, but pilots at Delta, Comair's parent, have stronger contractual rules to protect them, according to the Air Line Pilots Association.
At the same time, aviation groups and some members of Congress want a national policy to aggressively build more airports, like the policy that fostered the interstate highway system, said James K.

"Now that engines are a lot more efficient, a 20% improvement isn't worth as much as it was, so you're always working with diminishing returns and, at the same time, aviation is growing".
"Now it should do the same for general aviation".
At the same time, the aviation industry has been looking to reduce its greenhouse gas emissions though a number of approaches, including building more efficient aircraft and supporting the development and approval of new fuels.
The FDA is addressing this through benchmarking initiatives, in the same way that aviation authorities adopted computer-aided design over traditional physical testing.
It is found that with fleet-wide desulfurization of jet fuel, a 35% reduction in aviation NOx emissions would result in maintaining the same level of aviation-attributable early deaths in 2018 relative to 2005 levels, while an 80% reduction in NOx emissions would half aviation-attributable early deaths.
What we regard as harm in, for instance, civil aviation remains the same whatever advances may occur in aviation technology or practice.
