I got this email from Hale Irwin (not the golf pro on the Senior Tour), a customer and friend of mine. He "beat the air into submission" flying helo's during his time in the US Marine Corps.
We brought these Yamaha's in from Japan to Okinawa in the back of CH-46 Helicopters after the birds were overhauled in Tokyo:
Looks to me like he's wearing his flight helmet. Which is appropriate, 'cause he's flyin'!
