-- Description: This script will fly the drone to a location
-- To initialize the target location, local target_location = Location()
-- To make the location as altitude above home, target_location:relative_alt(true)
-- To set latitude, target_location:lat(latitude)
-- To set longitude, target_location:lng(longitude)
-- To set altitude, target_location:alt(altitude)
-- Use vehicle:set_target_location(target_location) to set the target location

-- create target location
