  The BD+40\degree4124 region was observed with high angular and spectral
resolution with the German heterodyne instrument GREAT in CO J = 13 \rightarrow
12 and [CII] on SOFIA. These observations show that the [CII] emission is very
strong in the reflection nebula surrounding the young Herbig Ae/Be star
BD+40\degree4124. A strip map over the nebula shows that the [CII] emission
approximately coincides with the optical nebulosity. The strongest [CII]
emission is centered on the B2 star and a deep spectrum shows that it has faint
wings, which suggests that the ionized gas is expanding. We also see faint CO J
= 13 \rightarrow 12 at the position of BD+40\degree4124, which suggests that
the star may still be surrounded by an accretion disk.We also detected [CII]
emission and strong CO J = 13 \rightarrow 12 toward V1318 Cyg. Here the [CII]
emission is fainter than in BD+40\degree4124 and appears to come from the
outflow, since it shows red and blue wings with very little emission at the
systemic velocity, where the CO emission is quite strong. It therefore appears
that in the broad ISO beam the [CII] emission was dominated by the reflection
nebula surrounding BD+40\degree4124, while the high J CO lines originated from
the adjacent younger and more deeply embedded binary system V1318 Cyg.
