Shooting from choppers is a game changer but teams are learning from scratch, working at break-neck pace in such dangerous terrain that an accident is always on the cards.

Shooting deer from choppers may be a game changer but everyone is learning from scratch. Working in such dangerous terrain, an accident is always on the cards. As shooter Jeff Carter puts it, "there were no margins for error."

Pioneering pilot Tim Wallis crashes his first chopper within ten days of getting it. A series of accidents and fatalities follow, rocking the industry.

Each man reacts differently but almost everyone smokes. Veteran shooter Pete Campbell recalls the stress of flying "in one of those damn machines."

"I'd probably go through about two pack of cigarettes. I dunno, it was just the height that scared you and this was the safest time in the whole lot."

Many shooters drink every night after work, probably to calm the nerves and avoid dealing with the stress of this dangerous work. But families suffer as a result and alcohol becomes a major factor in fractured marriages.

The consolation (and the lure) is big bucks. The men are earning huge money for the time and spending it on new cars, land and or fancy furniture for the missus. A few wise ones save their money.

But the money doesn't compensate wives and families for the long periods when they're left alone wondering, as the accidents mount, if they'll see their husbands again.
