Episode notes
Iran Ultimatum Risks Global Energy Shock
- President Trump issued an ultimatum to Iran to reopen the Strait of Hormuz or the U.S. would "hit and obliterate" Iran's power plants.
- Closing the strait threatens one-fifth of global oil and LNG, sending U.S. gas near $4 a gallon and risking a major humanitarian crisis if power infrastructure is targeted.
Deadly LaGuardia Runway Collision
- An Air Canada plane collided with a fire truck while landing at LaGuardia, killing both pilots and injuring truck occupants and passengers.
- Air traffic control had cleared the truck to cross responding to another flight's report of an odor, then urgently ordered it to stop seconds before impact.
