  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 (PWN)]. We showed, however, that the
association could be real if both objects are the remnants of an off-centred
cavity supernova (SN) explosion.
