*Title*: The SOFIA Legacy Project FEEDBACK

*Abstract*: FEEDBACK is a Stratospheric Observatory for Infrared
Astronomy (SOFIA) legacy project using the upGREAT heterodyne receiver
to map the [CII] 158μm line in Galactic molecular clouds. It aims to 
study the
interaction of massive stars with their environment in a sample of sources
that span a range in stellar characteristics from single OB stars, to
small groups of O stars, to rich young stellar clusters, to mini
starbursts.
The aim of these observations is to quantify the mechanical energy
injection and radiative heating efficiency in regions dominated by these
different processes (stellar winds, thermal expansion, radiation
pressure). This Legacy Program takes full advantage of the unique
capabilities of the upGREAT/SOFIA combination: the high spatial (14") 
and spectral
(sub-km/s) resolution of the 14 element upGREAT heterodyne spectrometer
coupled with the nimble telescope of SOFIA allows for efficient mapping
of the [CII] line over large areas. With a total observing time of 96h,
we will cover ~6000 arcmin^2 in 11 prominent Galactic sources. [CII]
observations, together with the less explored [OI] 63μm line (observed
in parallel), provide an outstanding data base for the community and 
will serve as a
starting point for many studies and follow-up observations.
