The National Transportation Safety Board has officially blamed the August 2000 plane crash that killed a former state senator on the pilot..
A final report appeared on the NTSB's web site this morning - a year and four months after the Piper Malibu Mirage carrying Thomas Allgood Sr., 71; his wife, Thelma, 61; and their dog Oz exploded upon impact with a brick wall outside Daniel Field.
The probable cause, according to the report, was improper preflight planning and preparation by pilot Stephen Patterson, 51, who took off with a cargo load well above the Piper's weight limit.
Other factors included taking off from a short, upward-sloping runway, and Mr. Patterson's elevated glucose level at the time, according to the NTSB.
A toxicology exam showed Mr. Patterson's glucose level at 1,175 mg/dl in a urine sample. Medical records revealed he had hypertension and diet-controlled diabetes, the NTSB report said.
Dr. Ian Herskowitz, an endocrinologist at University Hospital specializing in metabolic disorders, said normal blood glucose levels range from 70 to 110 mg/dl before eating, and no higher than 140 after. High levels can affect mental and cognitive abilities, but a number obtained from a urine sample rather than a blood sample is difficult to interpret without knowing more about the patient, he said.
