Passengers on a flight from Las Vegas to Atlanta passed out and needed to be revived with oxygen on Monday. The incident happened as Phoenix appears set to shatter another heat record for the 19th straight day.

The passengers had to be evacuated from the Delta Air Lines aircraft at Harry Reid International Airport because of the extreme heat.

Fox News field producer Kirsta Garvin was also on board, and she claimed that the pilot explained that they would be returning to the gate following a number of emergencies.

The incident as Phoenix prepares to set a record today for the 19th consecutive day with a high of 110 degrees. Little relief from the oppressive heat has been provided by the nights. Phoenix’s midnight low on Tuesday was only 94 F (34.4 C), a record-breaking ninth day without a temperature below 90 F (32.2 C).

According to reports, the situation got worse, and flight attendants could be seen rushing up and down the aisles carrying oxygen tanks as passengers started passing out.

Garvin claims that due to the heat on board the airplane, at least five passengers had to be removed off the flight. Due to the large number of sick persons, Garvin claimed that the decision was made to evacuate everyone and attempt to cool the aircraft.

The staff had also become ill due to the heat, she added in a later update to her Twitter thread. According to the National Weather Service, the airport’s temperature on Monday varied between 111 and 115 degrees. Delta Airlines revealed that they had been looking into the matter in a statement.

A spokesperson said: ‘We apologize for the experience our customers had on flight 555 from Las Vegas to Atlanta on July 17, which ultimately resulted in a flight cancellation.

‘Delta teams are looking into the circumstances that led to uncomfortable temperatures inside the cabin and we appreciate the efforts of our people and first responders at Harry Reid International.’
