On 13 December 2022,a couple was driving through the Angeles National Forest near Los Angeles,CA,USA,when their car slid off the road,plowed 100 m down a steep hillside,and landed upside down at the bottom of a canyon[1].Although the couple suffered only minor injuries,they were trapped in the canyon,and in the remote area the passenger could not get any reception on her iPhone 14 cellular phone.Still,she was able to send an SOS through a new feature on the phone that routes such messages via satellites[2].Rescuers alerted to the couple’s location airlifted them out of the canyon later the same day.
