  We present a study of the kinematics of the ionised gas in the nearby spiral
galaxy NGC 2403 using deep long-slit spectra obtained with the 4.2-m William
Herschel Telescope. The data show the presence of a halo component of ionised
gas that is rotating more slowly than the gas in the disk. The kinematics of
this ionised halo gas is similar to that of the neutral halo gas. On small
scales, broad line profiles (up to 300 km/s wide) indicate regions of fast
outflows of ionised gas. We discuss these new results in the context of
galactic fountain models.
