63. Three airlines each operate a single daily flight between Boston and London. Each flight is operated with a different widebodied jetliner, each built by a different manufacturer. Identify each airline and the respective widebody it flew.
I'm wondering if this was the period when Northwest had a shot at a range of European destinations from Boston ? If so, they possibly used a DC-10, and diluted the traffic for TWA who might downsize from the longstanding 747 to a Tristar. BA probably hung in there with a 747. Northwest would have to serve Gatwick, the others Heathrow.
