Why was the flight postponed?

May I have the attention of those traveling on Chav Airlines flight 742 from Hong Kong to Paris? The flight has been postponed for two hours because of mechanical problems with the plane. Please be advised that we do not recommend leaving the airport terminal in the meantime. To show our appreciation for your patience, the airline is giving 30 dollar meal vouchers to passengers on this flight. Just line up at the counter and present your boarding pass to our ticket agents to receive one. We are very sorry for the delay. Thank you for your understanding.
