1. On high wing military transports is has been used in some contries.
2. However, as on the C-17, underwing engines blowing on flaps is also
a viable way to do this.
3. Having engines under the wing makes for much easier maintenance
access and replacement.
4. On commercial aircraft, the wing is almost always low mounted for a number
of reasons.  Mounting the engines over the wing would product entirely
unacceptable noise levels in the cabin.  There wasa German Bizjet that
used this config and that was one of the reasosn it wasn't a major market
success.
