An unconscious tree trimmer stranded high above a San Jose neighborhood was dramatically airlifted to safety Friday after suffering a medical emergency while working roughly 75 feet up a palm tree.

Emergency crews rushed to the 2900 block of Sunburst Drive around 10 a.m., where the worker had become incapacitated while cutting the tree, according to the San Jose Fire Department.

Initial attempts to reach him from the ground failed due to the height and distance from the street.
