A supermarket that borders the Ottawa International Airport is warning customers
against losing their plastic shopping bags because they could blow onto the
runway and cause problems for aircraft. T&T Supermarket, which opened at the
airport’s northern border five years ago, has posted signs saying “please return
any unwanted bags” that include a graphic of a plastic bag blowing toward an
airplane. via
