Looking up the name and some articles hasn't turned up, for me, that particular claim, but Amory Lovins has railed against allowing a local airport to expand to allow larger aircraft to operate from it. The gist I am getting is that there are some wealthy Aspen residents who want to operate private jets that are larger than the current commercial service and the FAA is saying that the current operations don't require a larger facility.
Probably a topic for Jetblast over suitability of airport expansion.
If there is a link to a technical claim that could be interesting.
