This request seeks the following information regarding the aircraft operated by the Mosquito Research & Control Unit for mosquito-control operations:

1. The age of the aircraft and its registration number.
2. The annual cost of operating the aircraft, preferably for each of the last three financial years.
3. The number of flight hours flown by the aircraft in each of the last three years.

If available, I would be grateful if the annual operating cost could include fuel, maintenance, insurance, crew, and other directly attributable operating expenses.
