The CH-53 Sea Stallion helicopter's rotor blades contain a spar filled with pressurized nitrogen gas, which leaks out if a crack forms, causing a visible barber-pole indicator to shift as a ground-check warning. Because engineers in the 1960s couldn't rely on wireless electronics surviving inside a spinning rotor head, they developed IBIS, an Inflight Blade Monitoring System that uses a small radioactive source within the same pressure indicator to alert pilots mid-flight if a blade is failing.
A man who plugged in his electric vehicle at a car dealership was later charged $418 for the electricity used, far exceeding typical charging costs. The steep bill has drawn attention to how dealerships price EV charging for customers who use their facilities.

The Transportation Security Administration has launched a program allowing certain people without boarding passes to clear security checkpoints so they can accompany or meet passengers at the departure gate. This practice was common before the September 11, 2001 attacks but was eliminated afterward as airport security tightened nationwide. The new initiative marks a limited return of that pre-9/11 gate access for specific individuals.
