  Jets and outflows are the early signposts of stellar birth. Using the UKIRT
Wide Field Infrared Survey for H2 (UWISH2) at 2.12 micron, 127 outflows are
identified in molecular cloud complexes Vulpecula OB1 and IRDC G53.2 covering
12 square degrees of the Galactic plane. Using multi-wavelength datasets, from
1.2 to 70 micron, 79 young stellar objects (YSOs) are proposed as potential
driving sources, where, $\sim$ 79% are likely Class 0/I protostars, 17% are
Class II YSOs and the remaining 4% are Class III YSOs. The outflows are
characterized in terms of their length, flux, luminosity and knot-spacing. The
identified outflows have a median lobe length of 0.22 pc and 0.17 pc for
outflows in Vulpecula OB1 and IRDC G53.2, respectively. Our analysis, from the
knot spacing, reveals a typical ejection frequency of $\sim$ 1.2 kyr suggesting
an intermediate type between the FU-Ori and EX-Ori type of eruptions in both
cloud complexes. Furthermore, the physical parameters of the driving sources
are obtained by performing radiative transfer modelling to the observed
spectral energy distributions (SEDs), which suggest that the outflows are
driven by intermediate mass stars. Various observed trends between the outflow
properties and the corresponding driving sources, and various interesting
outflows and star forming sites, including sites of triggered star formation
and protocluster forming clump with clusters of jets, are discussed. The
obtained results and the identified jet-bearing protostellar sample will pave
the way to understand many aspects of outflows with future high-resolution
observations.
