Slack's comments came just hours after Transport Minister Mike Henry outlined several findings by investigators probing the December 22 accident.
One of those findings, Henry reported, was that the pilot of flight 331 insisted on landing on runway 12, instead of using runway 30 that was suggested by Jamaican air traffic controllers concerned about the heavy tailwind.
Other facts unearthed by investigators in the 15-day-old investigations are:
Had enough fuel
In addition, Henry said the flight plan listed Grand Cayman as the alternative airport, and that the aircraft had enough fuel to make the trip.
Slack, who looked over all the findings released yesterday, said it was clear that the pilot made one bad decision after another, starting when he shrugged off local air traffic controllers and insisted on using runway 12.
"He had an opportunity to do something safer and he passed on it ... he was gambling with the lives of these people," said Slack, who is also a pilot.
Speaking to The Gleaner from Texas, the former NASA engineer said the pilot had a second opportunity to correct the first mistake by "turning around and going to Cayman", as was indicated in the flight plan.
