With a great roar and a whirlwind of dust and grass, this C-17 demonstrates its ability to reverse taxi under its own power. Seen at Wings over Wine Country 2010.

A very old DC-6 (delivered Dec 1948), now converted to firebomber. The signs of frequent use of red fire retardant are clearly visible. Macavia's ship 20 does carry titles, almost unreadable just below the logo on the nose.
This aircraft was sold as 9Q-CPL in 1994 and became EL-WNH in 1997. By 2007 it was in use as a fire trainer at Lanseria, South Africa, and it was still there in derelict condition by 2015.
