The recent earthquake in Hawaii, and subsequent temporary airport closure got me thinking. What would happen in the case of WS (for example) being about 30 minutes out, and the airport closes. I highly doubt the 737 would be able to return to the mainland, and if the earthquake was severe enough to damage the runways, what alternatives would there be?
I'm positive the FAA has looked at this, but does anyone know "What next?" Other than the Hawaiian Islands, the next closest runway I'm aware of is Midway, some 1200 miles further west, but can a 737 carry that much fuel for an extra 2 hours?
