An extended XMM-Newton observation of the luminous narrow line Seyfert galaxyPG 1211+143 in 2014 has revealed a more complex highly ionized, high velocityoutflow. The detection of previously unresolved spectral structure in Fe Kabsorption finds a second outflow velocity component of the highly ionizedwind, with an outflow velocity of v~0.066+/-0.003c, in addition to a stillhigher velocity outflow of v~0.129+/-0.002c consistent with that first seen in2001. We note that chaotic accretion, consisting of many prograde andretrograde events, offers an intriguing explanation of the dual velocity wind.In that context the persisting outflow velocities could relate to physicallydistinct orientations of the inner accretion flow, with prograde accretionyielding a higher launch velocity than retrograde accretion in a ratio close tothat observed.
