suppose an imaginary fireworker that launches rockets at a v=c/2 ( could be any velocity, but near light), and the rockets are programmed to explode at certain time T
according to relativity there must be a certain delay in the explosion seen from the fireworker frame , and he should see the explosion at T*(2/sqrt3), or also that means that the explosion really occurs ((2/sqrt3) -1) seconds after T

However he could reason also in this way: he knows the rocket has traveled during T*(2/sqrt3) at c/2 velocity, hence, multipliyng , the rocket is now at
c*T/sqrt3 meters from home, dividing this for c, he obtains that the explosion ocurred T/sqrt3 seconds after T

so, my question is, if there is something wrong in this argument and where?
