This is an action of tort to recover the value of clothing and personal effects worn by, and on the person of, the plaintiff at the time of the accident hereinafter described. The case comes before this court on appeal by the plaintiff from the decision of the Appellate Division of the Municipal Court of the City of Boston dismissing the report,
The defendant offered and the trial judge received the testimony of the pilot and that of a bystander who had a pilot’s license. The bystander testified that when the plane took off it went up normally, although in a few seconds it made the dip referred to in the plaintiff’s testimony. The pilot testified to his handling of the machine, and further, that he had piloted the same machine on a previous trip
The plaintiff, claiming to be aggrieved by the rulings and refusals to rule as requested, reported the case to the Appellate Division for determination.
The special facts found, coupled with the general finding for the defendant, import that the judge, as the trier of facts, disbelieved the testimony of the plaintiff that while the plane taxied on the ground to the place where it was to take off, the right wing motor backfired and emitted clouds of smoke, and that when the pilot “revved” the motor, the right wing motor did not revolve at the same speed as the other motors; and that he found, on the testimony of the bystander and of the pilot, that the plane took off normally, that both motors when the plane left the ground were “revving” at the same rate, and that the reason one motor was “revving” at fewer revolutions per minute than the other motors while the plane was on the ground was because the plane was being steered in that manner by the pilot. Assuming a finding that when the plane took off it went up normally, it would follow that the backfiring, the emission of clouds of smoke, and the fact that the right wing motor did not revolve at the same speed as the other motors when the pilot “revved” them, would fall into the domain of both adjective and substantive law, known as the assumption of risk, and would be the agreement of the plaintiff to assume the ordinary risks of air transportation.
The elimination of the facts in controversy which resulted from the finding for the defendant leaves for determination the issue whether a passenger for hire in a" privately operated airplane can invoke the rule of res ipso loquitur should the right wing motor go dead and the right side of the plane tip, a few seconds after leaving the ground, with the result that, though the pilot made frantic efforts to right the plane, it was steered toward the water and immediately made a nose dive into the water. It is as
The principle of res ipso loquitur only applies where the direct cause of the accident-and so much of the surrounding circumstances as were essential to its occurrence were within the sole control of the defendants or of their servants. Reardon v. Boston Elevated Railway,
There is nothing in the record to indicate by whom the airplane was inspected. It does not appear that the inspectors, to whom the pilot, according to his testimony, turned over the airplane on his arrival and from whom he received it a few minutes before he took off, were employed by the defendant. They may have been servants of an independent contractor or of one conducting an independent business, to whom as mechanics skilled in aircraft the defendant in the exercise of a high degree of care committed the inspection and repair of the airplane. There is at present no common knowledge of which courts can take cognizance concerning the customs or usual practice of air transport companies as to operation, inspection and repair of their airplanes. There must be evidence. We are not as yet, in respect to the operation, care and characteristics of aircraft, in a position where the doctrine of cases like Ware v. Gay,
The judge properly found for the defendant, and the entry “Report dismissed” must be ■
Affirmed.
