*145 MEMORANDUM AND ORDER
In this рroducts liability suit the jury rendered a verdict in favor of defendant. Pending are plaintiffs’ motion for a new trial and defendant’s motion for a dirеcted verdict. Plaintiffs assert twelve grounds in support of their motion, which we briefly address in turn.
Plaintiffs’ major legal contention is that the Court errеd in allowing Eugene J. Kielb, design engineer for the Bobcat Model M-610, to testify that some 34,000 M-610 loaders were built from 1972 to February, 1978, that these machines represented 74,-000 machine years of exposure during that period, and that he was aware of no other accident involving а person getting on or off or leaning out of the machine while the motor was in operation. The point was that a considerаble volume of the questioned equipment was in use, without injuries that plaintiffs claimed could be anticipated from the type of usagе in question. Plaintiffs rely on
Schillie v. Atchison, Topeka & Santa Fe Ry. Co.,
Cases deciding the issue as a matter of. federal law have generally, if not universally, held that evidence of the absence of prior accidents is relevant and admissible, assuming an adequate foundation is established regarding comparability of circumstances.
DeMarines v. KLM Royal Dutch Airlines,
Plaintiffs also contend that it was error to submit a contributory fault instruction to the jury, in that there was no evidencе to support the conclusion that Dennis Sturm “[knew] the facts which create the danger and ... that he comprehended] and appreciate^] the danger itself.”

v.
Rockwell Graphic Systems, Inc.,
*146 Two of plaintiffs’ assignments of error, # # 7 and 12, relate to damage issues. We need not consider whether any error was committed with respect to these items due to the fact that the jury rendered a verdict for defendant. Error, if any, was nonprejudicial.
Three of plaintiffs’ assignmеnts of error, # # 4, 5, and 8, involve the introduction of evidence concerning lock-out systems for hydraulic booms. Some of this information may have been sought on redirect examination that was beyond the scope of cross examination and on matters not covered by the direct examination. In addition, the proffer of the evidence in question related to a modification of the views of рlaintiffs’ expert that had not been disclosed to defendant in answers to interrogatories or otherwise during discovery. See plaintiffs’ answer to interrogatory 13(b), filed April 16, 1979. Introduction of the evidence would, therefore, have been prejudicial to defendant and would have materially changed the issues in the case. Plaintiff counters that defendant should not have been surprised that the issue of interlоcks would be in the case because
defendant’s
expert had been questioned on the matter during his deposition. The fact that Dr. Morrell was quеstioned on the lock-out systems did not, however, provide notice to defendant that plaintiffs had developed and would be relying оn a defect theory relating to these systems, so that defendant could be fully prepared for trial on this issue. If plaintiffs were serious аbout the issue, rather than presenting a belated make-weight theory at trial, pretrial disclosure should have been made.
Voegeli v. Lewis,
Plaintiffs allege error in not being allowed to argue to the jury that defendant was a “calloused manufacturer of equipment in placing on the market a machine that they know, or should have known would eventually kill.” Callousness is defined as “hаrdened in sensibility; ... without regard for the feelings or welfare of others; indifferent to the suffering of others.” Webster’s Third New International Dictionary. Defendant’s indifference or сallousness would relate to punitive-type damages for causing death under aggravated circumstances, which were not sought in this сase. The argument was, therefore, properly prevented, and, in any event, does not go to the issue of liability, on which the jury rejеcted plaintiffs’ proof.
Plaintiffs’ final assignment of error is that defendant should not have been allowed to examine witness Roop on matters that were beyond the scope of direct examination. We agree with plaintiffs that matters were presented that were not proper cross examination. For this reason the Court allowed examination of Mr. Roop with regard to his familiarity with the Bоbcat and warnings to Sturm as if on direct examination in defendant’s case. Leading questions were barred, over strenuous objection by dеfendant. This procedure negated the need to have Roop recalled as a witness for defendant and was not confusing to the jury, even if the testimony may be considered to have been allowed out of order. Rule 611(a), F.R.Evid.
For the reasons stated above and for good cause shown, it is hereby
ORDERED that plaintiffs’ motion for new trial is denied.
ORDERED that defendant’s motion for a directed verdict is denied as moot.
Notes
. For purposes of this motiоn we may assume that current Missouri law would still exclude this evidence.
