Mal is a great guy and a fantastic contributor to safe aviation. Would do anything for anybody often without having to be asked.
Many pilots will recall that when the HF was bad and one couldn't hear any FSU at all, the one voice that always seemed to be there to pick up your taxy call or your sartime cancellation was Mal's. Somehow his voice always seemed to defy ionospherical physics and get through.
I heard one story where his famous voice actually saved an IFR pilot from certain death, after he had inadvertently fallen asleep while on descent into a remote airport at night after a long trip. I believe the pilot eventually woke up after Mal's unique voice tones finally drummed into his subconscious, just in time to prevent the aircraft from contacting the ground.
Go well, Mal - you are a FS (and industry) legend and not many of us can lay claim to that.
