During the early 80's a Mustang was parked in front of VH Aviation's hangar in Canberra.
It had an F27 Dart engine installed.
Word at the time was that it was installed upside down and the exhaust was on the wrong side, when power was used, the prop wash funnelled the exhaust straight onto the canopy and the pilot could not see a thing!
It sat their for a number of years then disappeared.
