The court heard Kyagera was preparing to take off at 8.30am on Monday, December 22, after drinking a “considerable amount of alcohol” at a family party on Saturday followed by several glasses of wine on Sunday.
A breath test showed 45 micrograms of alcohol in 100ml of breath, five times the 9mcg limit for pilots. A blood test at 11.45am revealed 42 milligrams in 100ml of blood, twice the 20mg limit.
