TEMPERATURES HAVE BEEN UNUSUALLY HIGH AND APPROXIMATE OAT AT THE TIME WAS 93 DEGREES F. PREVIOUS DAY TEMPERATURES EXCEEDED 118 DEG F. AIRCRAFT IS PAINTED BLACK AND WINDOW OBSERVED TO BE EXCESSIVELY SOFT. WE DETERMINED THAT LATENT HEAT WAS A CONTRIBUTING FACTOR TO WINDOW POPPING OUT AS NO SIGNIFICANT DAMAGE WAS NOTED ON THE WINDOW FRAME, SEAL OR WINDOW ITSELF ASIDE FROM INCREASED PLASTICITY DUE TO HEAT.
