We present a measurement of the polarization- temperature angular cross power spectra, < TE > and < TB >, of the cosmic microwave background. The result is based on similar to 200 hr of data from eight polarization- sensitive bolometers operating at 145 GHz during the 2003 flight of BOOMERANG. We detect a significant < TE > correlation in the l-range between 50 and 950 with a statistical significance of > 3.5 sigma. Contamination by polarized foreground emission and systematic effects are negligible in comparison with statistical uncertainties. The spectrum is consistent with previous detections and with the ``concordance model'' that assumes adiabatic initial conditions. This is the first measurement of polarization- temperature angular cross-power spectra using bolometric detectors.
