PUDLOWSKI, Presiding Judge.
Plaintiffs appeal from the judgment rendered in a wrongful death action brought by the widow and six minor children of the deceased, Taft Barnett. Suit was instituted against M & G Gas Co. (hereinafter referred to as M & G), Exxon Chemical Co. (hereinafter referred to as Exxon) and William and Beulah Barnett, the deceased’s parents. The cause of action arose out of an explosion and fire at William and Beulah’s summer residence in Fredericktown, Missouri in May, 1975. Taft Barnett was fatally injured. The widow’s brother, Raymond Purcell, also sustained injuries due to the explosion and joined the action as a plaintiff. Plaintiffs and defendants dispute vigorously the cause of the explosion and fire which resulted in the injuries above. Plaintiffs attribute it to an LP gas leak. Defendants presented evidence that the explosion was caused by the accumulation of gasoline vapors.
At the close of plaintiffs’ evidence, the trial court directed a verdict in favor of William and Beulah Barnett. Further, it directed a verdict in favor of M & G and Exxon following the close of all the evidence. Plaintiffs’ first three points on appeal alleged that the trial court erred in so directing the verdicts in favor of the defendants since the plaintiffs contend they had made a prima facie case against each defendant for their particular acts of negligence. We do not agree.
We initially note that a directed verdict is a drastic measure. In passing upon the propriety of such a motion, we must apply the fundamental and settled rules that we consider all of the evidence in the light most favorable to the plaintiff, accept it as true where it is not entirely unreasonable or opposed to physical laws, accord to plaintiff the benefit of all favorable inferences deducible from the evidence, reject all unfavorable inferences and disregard defendant’s evidence except insofar as it aids plaintiff’s case. Joiner v. Kurt’s Chip-A-Way Park, Inc., 510 S.W.2d 773, 774 (Mo.App.1974); Cantrell v. Superior Loan Corp., 603 S.W.2d 627, 634 (Mo.App.1980). When challenged on appeal, a verdict directed against plaintiff will fall “unless the facts in evidence and the legitimate inferences to be drawn from such facts, are so strongly against the plaintiff as to leave no room for reasonable minds to differ.” Abel v. Campbell 66 Express, Inc., 378 S.W.2d 269, 271 (Mo.App.1964); Braun v. General Motors, 579 S.W.2d 766, 769 (Mo.App.1979).
Viewed in this light plaintiffs’ evidence established that William and Beulah Barnett were the owners of a small 5 room house in Fredericktown, Missouri with overall dimensions of 30 X 15 feet. This house contained a kitchen of approximately 9 X 15, a living room of 12 X 15, a bedroom of 9 X 12 and a small utility room and bathroom. There was no basement, only a
