I have rode in huey's, ch46's, and ch53's.

Scariest ride was going from Okinawa to Korea on a ch46 all that water. No where to land. Thank god I had good pilots that could read instruments.

Two day trip, day one Okinawa to Iwakuni. Day two Iwakuni to Korea. And then back two months later.

Got lots of sleep. Like sleeping on a huge noisy vibrator. Ah the good ole days!
