 1. Who receieved a 1.5kg pckage?

 2. What is the total weight of all his sent packages?

 3. Which pilots handled that stuff?

 4. Add to the database a 100.3kg package sent by Ray Bradbury to Leo
    Wong, the day after Leo's last got something. Of course Ray would
    chose the person with the most experience to handle the delivery.

 5. Who sent the krill to whom?

 6. What planets is Amy not allowed to land on?

 7. Change the weight of the heaviest package to be one kilogram lighter.

 8. Make a table of the total mass sent and received by each client.

 9. Update the database with a new employee, Kira Nerys, who brought
    100kg of plasma rifles from Lrrr on Amazonia to Jean Luc Picard on

    planets.)
