Fourier-transform spectra (4000-7000 kaysers) of FU Ori and V1057 Cyg show strong water vapor and weak CO in absorption. Their optical spectra remain those of F-G supergiants, however. The infrared spectra demand reappraisal of the FU Orionis phenomenon. Three models are discussed: (1) a single star with a circumstellar dust shell; (2) a binary in a common circumstellar envelope; and (3) a rapidly rotating star with a flattened, possibly disklike, shell. The first model can clearly no longer explain the observations; of the other two models, the rapid rotator appears the more promising, although neither can be strongly preferred on the basis of the present data.
