At first, air-traffic controllers didn’t seem alarmed when Mr. Russell climbed into the cockpit of an airliner Friday evening. The theft exposed the aviation vulnerabilities that persist even after efforts to enhance security following the Sept. 11, 2001, terrorist attacks.

Uber drivers take riders the long way—at Uber’s expense. Many drivers are employing a practice known as longhauling—taking an unnecessarily longer route to a destination to drive up a fare. But unlike taxis, where passengers “get taken for a ride,” it is ride-hailing companies such as Uber that are responsible for covering the bigger bill.

Banks are finally starting to pay their depositors. The grim decade in which savers earned near nothing on their bank deposits is ending.

Today’s Question and Answer

Responding to Friday’s question on automated savings in 401(k) plans being withdrawn well before retirement:

• Robert Nagel of Australia shared: “We are all living longer and someone ultimately needs to pay the living expenses of all retirees. Why should we not all be expected to contribute to our own retirement proportionate to our own circumstances to do so?”
   
• Bonnie Fitch of Indiana wrote: “If anyone would ask me for advice, I would highly suggest doing any and all remodels before retirement, but still be debt-free at least one year before retirement so you can invest for the future.”
   
• Karin Bonding of Virginia said: “Automated savings for new employees has proven to raise participation.  When employees leave a company, improved level of education/information about the detrimental effects to the employee’s retirement must be part of the leave package.”
