The association of PSR B1757–24 and the supernova remnant (SNR) G5.4–1.2 was recently questioned by Thorsett et al. (2002) on the basis of proper motion measurements of the pulsar and the “incorrect” orientation of the vector of pulsar transverse velocity (inferred from the orientation of the cometary-shaped pulsar wind nebula). We show, however, that the association could be real if both objects are the remnants of an off-centered cavity supernova explosion.
