Published on Sep 8, 2015P-2<br /> (P2V-5) Neptune Tanker 05 is seen in this brief video with engines <br />running, as the plane taxies to parking and shuts down. Listen to those<br /> R-3350 engines; hear the brakes squeal. Well-maintained Neptunes, some <br />more than 60 years old, serve in the seasonal wildfire battles of the <br />western United States.
