I feel as if someone is going to do some terroristic damage (eg 9/11), a turboprop is hardly what they're going to hijack is it? The Mokulele planes only have a curtain between you and the pilots.. which is often open. It's fun! Get the best views too, since it flies below 10k. Mokulele has no TSA outside of HNL departures, so other departures (eg KOA, MKK, OGG) are TSA free. It's very nice.
