There is a variety of information on this at http://www.flatoday.com/today/ and http://www.esrin.esa.it/. The 6 Jun press release says they are loking at software, but as nearly as I could tell there are also other causes which are being considered. So if anyone wants to post solid information, great, but IMHO, there isn't much point in speculating. > I don't think one has never see number 1 of any rocket succeeded in > the aerospace industry history. Check out Jonathan's space report #289 at http://hea-www.harvard.edu/QEDT/jcm/space/jsr/jsr.html. He has a list of the first flights of new (not upgraded) first stages. Maybe half of them have succeeded (whether the upper stages, if any, succeeded also he doesn't list).
