"Record-breaking Winds Propel Passenger Planes to Supersonic Speeds Over the Atlantic"

Freak winds in the Atlantic jet stream propelled five commercial flights to speeds exceeding 800mph, faster than the speed of sound, cutting their travel times significantly. While this allowed for earlier arrivals, it also led to more severe turbulence due to faster jet stream speeds, a consequence of global warming. Scientists suggest that redirecting flights to take better advantage of favorable winds could save fuel and reduce carbon emissions, but the trade-off is an increase in turbulence.
