1989 Alaska Milkmen season

The 1989 Alaska Milkmen season was the fourth season of the franchise in the Philippine Basketball Association (PBA).

Occurrences
Going into their April 13 do-or-die encounter for the last semifinals berth against Añejo Rum 65, coach William "Bogs" Adornado was asked not to sit on the Alaska bench, the Airmen had an "open coaching among players" during that game with assistant Aric del Rosario and team owner Wilfred Uytengsu calling the shots. The next day in a meeting between Adornado, team manager Joel Aquino and owner Wilfred Uytengsu, Adornado was advised by the Alaska management to resign and gave up his position. In a letter of resignation, Adornado accepted responsibility for the team's dismal showing but blamed the management for their failure to get the services of a suitable import, Aquino handled the team starting the semifinals and for the rest of the first conference.

Tim Cone, a member of the vintage panelists, guided the Airmen to a third-place finish in the Open Conference and soon accepted coaching chores for Alaska starting the Fiesta All-Filipino.

Notable dates
