Boeing debuts the first commercial jetliner.

The four-engine plane carries 181 passengers and flies up to 5,280 miles on one tank of fuel. The first flight goes from New York to Paris and ushers in a new era of air travel.

American Express builds on a service offered by Diners Club by issuing a credit card that can be used at many different locations, beyond restaurants.

The first cards are made of paper, with the customer’s name and account number typed on the front.
