The measurement of the cosmic microwave background taken during the MAXIMA-1 flight was used to estimate the bispectrum of cosmological perturbations. An estimator for the bispectrum was proposed that appropriated in the flat sky approximation and was applied to the MAXIMA-1 data. This measurement placed constraints on models of the inflation and the bispectrum analysis of the data showed the consistency of the data with Gaussianity.
