There they were joined by more hijackers and demanded the release of 40 Palestinians held in Israel and 13 other detainees imprisoned in Kenya, France, Switzerland, and West Germany.
If these demands were not met, they threatened to kill hostages on July 1.
Journalist Bruce McDougall, who worked for The Star in 1976, said in an article about stoic Cantabrians following the February earthquake: "Hardie risked his life by secretly writing details of the terrifying conditions inside the jet down his arm, for an exclusive story in The Star.
"That Cantabrian spirit will get this now earthquake-stricken city through its darkest days."
The hijackers held the passengers hostage for a week in the transit hall of Entebbe Airport. Some hostages were released, but 106 remained captive.
On July 1 the Israeli government offered to negotiate with the hijackers in order to extend the deadline to July 4.
On the new deadline the Israeli forces raided the airport terminal. Three hostages were shot and died in the crossfire, 10 were wounded.
The funeral for Mr Hardie, who worked at The Star for more than 25 years, is to be held today.
