Asuka Kasen

A Cartel SPANK plane is making its drop run over Liberty City. Asuka hands Claude a surface-to-air missile launcher and tells him to bring it down before delivery.
S.A.M. is the final mission in Grand Theft Auto III given to protagonist Claude by Yakuza leader Asuka Kasen from a Panlantic Construction Company construction site in Fort Staunton, Staunton Island, Liberty City.
Claude visits Asuka and Maria Latore at the construction site in Fort Staunton. Asuka informs Claude that a plane containing a number of SPANK drug packages is arriving at Francis International Airport in Shoreside Vale. Asuka advises Claude to travel to the airport by boat to avoid the airport security, so Claude drives over to a jetty in Bedford Point. He picks up a Rocket Launcher on the jetty and takes a boat to sail over to the southern end of the airport. He kills the Colombian Cartel gang members guarding the exit of the airport. A short time later, the plane containing the drugs lands at the airport. Claude destroys the plane with the rocket launcher, scattering the drugs all over the runway.
After the plane is destroyed, Claude retrieves the packages before the police arrive. After escaping from the police, Claude leaves the airport and travels back to the construction site with the drugs.
