. Comment on J0405+3803 . Our image contains a feature of 25 mJy at 14 mas E-NE from the brightest component. It is not visible in the Caltech-Jodrell (CJ) survey image at 5 GHz (Xu et al. 1995) obtained about 6 years earlier. The 1.6 GHz CJ image (Polatidis et al. 1995) does show an extended feature close to the position in question, but somewhat displaced toward west. VLBApls home page . Last modified: 16 Oct 2000

The principle of the existing reliability level of space engineering, and first of all, of rocket-launchers is laid into the milestone of the cosmonauts training (the successful launch of "Soyuz" space vehicle is close to 1, but it is less than 1), that causes a possible landing of space crews outside the regular landing site. ... However, search operations can be hampered by difficult meteorological and geographical conditions in the region of emergency landing. ...
