  Passage: Lydia Diaz Cruz is a Prima Ballerina who started dancing in Havana, Cuba, and trained with Fernando Alonso and Alicia Alonso.  As a young dancer, she was talent-spotted by a well-known British dancer and teacher from an earlier era, Dame Phyllis Bedells, who traveled to Cuba and regarded her as the most naturally gifted dancer she'd seen since Margot Fonteyn.  Early marriage and exile from Cuba in the wake of the Castro revolution put a halt to her career, which she resumed after the birth of her third child in the early sixties.  She went on to dance in the United States with Ballet Concerto in Miami, became principal dancer with the National Ballet of Washington, D.C., and has performed in principal guest roles with the National Ballet of Venezuela, Washington Ballet, Ballet Spectacular.

  Title: Operation Big Bird
  Passage: "Operation Big Bird" (Filipino: "Oplan Big Bird") was the attempt of the Philippine Government during the presidency of Corazon Aquino to recover the alleged US$7.5 billion of hidden accounts and assets of President Ferdinand Marcos and his family in the Swiss banks.  Conceived by Philippine banker Michael de Guzman, it commenced shortly after Marcos was forced into asylum in the United States.  Initially, Operation Big Bird did not recover any money with two differing reports by Representative Victorio Chaves and Senator Jovito Salonga.  Chaves laid the blame upon Salonga, Solicitor-General Sedfrey Ordoñez and the Swiss bank lawyers.  Salonga countered that Ordoñez had prevented the Philippine government from losing a large sum of money.  Evidence suggests that de Guzman acted in good faith on behalf of the new government but that a double cross may have been present.
