Roy Halladay was doing acrobatics and had high levels of amphetamines in his system when he lost control of his small plane and nosedived into the Gulf of Mexico in 2017, killing him, according to a National Transportation Safety Board report said.
Halladay had amphetamine levels about 10 times therapeutic levels in his blood along with a high level of morphine and an antidepressant that can impair judgment.
The maneuvers put loads of nearly two-times gravity on the plane, an Icon A5 -- a light sport two-seat amphibious aircraft that Halladay had purchased a month earlier.
On the final maneuver, Halladay entered a steep climb and his speed fell to about 85 mph, according to the report. The propeller-driven plane went into a nosedive and smashed into the water.
The report says Halladay, 40, died of blunt force trauma and drowning.
