I would guess a few of us have been in Teresa's position. I checked a guy into the jungle strips out of moresby where he pranged an islander a couple months later.. no-one died but a pax lost a limb. A guy I knew well.. AY checked a guy out into the Telefomin/Oksapmin area where trainee crashed his 206 and died on the very next trip there. He was very messed up about that and eventually became a figure of note within the PNG accident investigation scene.. working out his karma?.. who knows.
BTW Sharpie for your amazing list the Kokoda crash a/c reg is P2-MCB.
