M/V
I too flew on Maui a few months back. As you say Mount Haleakala is 10000ft+.
Was an odd trip - we took off in CAVOK 30 degree heat, and got to the top among wispy stratus and on the other side of the isalnd we were caught in a few heavy showers (the rain forest side out by Hana). Was certainly sporty in a few of the hovers over waterfalls.
All in all was a great trip (esp shutting down on a beach and having a glass of Champage on the beach
!) Was wondering though, were the pax like us and all honeymooners?
Bad news either way of course.
