I noticed this in a BBC report:
Just as my BBC colleague travelling with Barack Obama found, on Hillary Clinton’s aircraft, the press roll oranges up the incline towards the first class section, as the plane takes off. It is a case of fact and fiction becoming blurred – a “West Wing” tradition being applied to a candidate whose husband’s time in The White House inspired the TV series.
Just to correct the record, it was Ron and Nancy Reagan who started the tradition of rolling oranges down the aisle on campaign planes. And, memorably, on Halloween 1980 Ron rolled a pumpkin.
