44664: Spawn Missile
Copy the left-facing missile and flame templates at Missile_Object_Template (or the right-facing pair at Missile_Object_Template_2, entered at Handler_Missile_CopyTemplate2) into Object_Slot_1 and place them at this actor. The hit count is the level plus 8 (up to 99). Then jump to ShowLaserEstimate to show the laser estimate, unless 24946 is non-zero or Jetman's type is 42 or above with no lives left.
