Engineers yesterday found the same problem that occurred in the Number 2 engine of the Challenger in her Number 3 engine as well and pulled both engines today. NASA says the problem, a crack in a hydrogen fuel line, appears to be a design flaw in the new engines. Columbia's engines didn't have the ''improvement'' and thus didn't have the design. No word was given on the effect on STS-6's launch date.
