There are several slightly bizarre biographical snippets about people. First, figure out who they are. They are, in order:
Chiang Kai-shek
George HW Bush
Charles de Gaulle
David Ben-Gurion
Chhatrapati Shivaji
Leonardo da Vinci
Léopold Sédar Senghor
What do these people have in common? Each has an airport named for him. Take the airport codes:
TPE IAH CDG TLV BOM FCO DKR
Read down the middle letter of each code, and it spells PADLOCK, which is the answer.
