El Centro CA in the 70”s one week average temp was 121. I was there in the navy working on F8”s teaching pilots. TAD from Nas Miramar. There was a F4 group there also. One day close to 130 on the flight line a F4 hit afterburner never got off the ground plowed through a lettuce field.
I was a airframes troubleshooter had to carry your tools in a bucket of water and keep the bucket in the shade or the water was to hot to put your hand in.
We all got a letter of accommodation in our service record for flying 155 hours with average temp of 121. Back in the day..
