Forgive a SLF laywoman joining in. The Smith School's website has a more extensive message
here. It seems to go into a bit more detail about things.
There's a snazzy
pdf of the study's report if anyone's feeling that adventurous.
As for the Smith School itself, its
about page suggests that it's not really aviation-based or -focused. So even though they likely (we'd like to hope) had some experts in this field in, it might not have been their top priority.
