2 hospitalised after plane passengers were trapped on tarmac during Las Vegas heat wave.

Several passengers on a Delta Airlines flight from Las Vegas fell ill after getting trapped on the tarmac during a heat wave.

On Monday, Delta had to cancel Flight 555 from Las Vegas' Harry Reid International Airport to Atlanta after passengers began to get sick on board. At least five passengers passed out. 

With temperatures around 111 degrees, grounded passengers began to faint and soil themselves, forcing flight attendants to administer oxygen. First responders used stretchers to wheel passengers and at least one flight attendant off the plane, according to NBC news.

While federal policies mandate that passengers must be allowed off of a plane after three hours of waiting, there are no laws concerning heat.

Extreme summer heat has created similar circumstances in the past. In 2017, a baby went limp on a sweltering United Airlines flight, The attendants assured the mother that the cabin would cool once the plane was in the air, but the heat was already too much for the child. He lost consciousness while in his mother’s arms.
