The "Lando ordeal" was the name the Tonnika sisters used to describe an event involving at least themselves, the smuggler Han Solo, and smuggler Landonis Balthazar Calrissian. The ordeal was Solo's idea, yet he would blame the outcome of the event on the sisters.
Later, concurrent to the Galactic Empire's search for the Death Star plans, Senni Tonnika suggested it would be wrong for Solo to continue to hold the grudge against them for the ordeal, yet Brea Tonnika understood there was other history between them and Solo that soured their working relationship.
