The heat has been blamed for a flight cancelation to McCarran International Airport Monday afternoon.
While Alaska Airlines Flight 605 was preparing to take off, pilots detected an engine overheat light. The aircraft returned to the gate and 153 passengers and 6 crew members had to get off the plane.
The passengers were rebooked for travel Monday on later flights. The aircraft was deemed safe.
Temperatures reached a record high of 115 degrees at McCarran International Airport Monday.
Heat thins out the air, creating problems with liftoff and landing. On Sunday night, a plane set to land in Phoenix had to turn around because it was too hot -- 120 degrees. That is the cutoff temperature for planes to takeoff or land.
