The Sky Rider

The Sky Rider, the 1928 Alan James silent airplane inheritance family relationship action thriller (about a man trying to kill his relatives so he can gain an inheritance; he does so by planting a bomb in a plane they are riding in, and apparently an incredible dog named Champion helps save the day, including jumping from one airplane to another!) starring Champion the Dog (a very talented German Shepherd!), Gareth Hughes, Josephine Hill, J.P. Lockney, and John Tansey.
