PARKER, J.

Plaintiff’s sole assignment of error is to the signing of the judgment. This presents one question for decision: whether the facts found by the Judge are sufficient to support the judgment. James v. Pretlow, 242 N.C. 102, 86 S.E. 2d 759; Glace v. Throwing Co., 239 N.C. 668, 80 S.E. 2d 759; Rader v. Coach Co., 225 N.C. 537, 35 S.E. 2d 609.

There is neither finding of fact nor evidence, that the glider was “operated for any aviation training,” or that it was “maintained or operated for military or naval purposes.” Therefore, paragraphs (b) and (c) of the AviatioN ExolusioN Rider have no application to the facts found.

This leaves for our consideration this part of the Rider:

*447 “AVIATION EXCLUSION RlDER

Death of the Insured as a result of travel or flight in or descent from or with any kind of aircraft is a risk not assumed under this policy.

(a) If the Insured is a pilot, officer, or other member of the crew of such aircraft, is giving or receiving any kind of training or instruction, or has any duties whatsoever aboard such aircraft while in flight.”

There is no evidence or finding of fact that George Howard Scarboro “was giving or receiving any kind of training or instruction.” As plaintiff states in her brief “George Howard Scarboro was flying alone for his own purposes, namely for pleasure.” The Judge found as a fact that he was operating a single-seated aircraft, known as a glider, when it fell to earth, and in its fall he was fatally injured.

Plaintiff contends that the word “crew” used in the RideR means “the company of airmen who man an aircraft”; that the words “or other member of the crew” refer back to and limit the words “pilot, officer,” “and incorporates them into the general category, which follows, namely, “other members of the crew”; and that the language used means pilot, officer, of a crew of airmen. Plaintiff further contends that, considering the words of the Rider as a whole, the words “any kind of aircraft” refer to mechanical species of aircraft, and do not cover a single-seated glider as here; and that the words “such aircraft” refer to that species of aircraft. Plaintiff further contends that George Howard Scarboro was not a pilot of a crew, had no duties whatsoever aboard the glider while in flight, and that she is not excluded from recovering the face value of the policy by any provision of the Rider.

Attached to this policy and made a part thereof is a double indemnity provision for death through external, violent and accidental means, but “the agreement as to benefits under this provision shall be null and void if death occurs . . . (b) as the result of travel or flight in or descent from any species of aircraft if (I) the insured is a pilot, officer or other member of the crew of such aircraft, is giving or receiving any kind of training or instruction, or has any duties whatsoever aboard such aircraft while in flight, ... , or (III) the aircraft is operated other than by a duly licensed or certified pilot in the course of his regular employment in the transport of passengers for wages or salary . . . .” It is to be noted that plaintiff in her complaint did not seek to recover on- the double indemnity provision of the policy.

It is clear that the usual, ordinary and commonly accepted meaning of the word “glider” is that it is a form of aircraft. It is so defined in Webster’s New International Dictionary, 2nd Ed.: “Aeronautics. A form of aircraft similar to an airplane, but, without any engine.” *448 2 C.J.S., Aerial Navigation, Section 2, in Pocket Parts, gives the same definition. In Spychala v. Metropolitan Life Ins. Co., 339 Pa. 237, 13 A. 2d 32, the Court said: “It thus appears that a glider is a type of airplane which is not equipped with a motor . . . .”

It is equally clear that George Howard Scarboro was pilot of this glider when it fell. In Wilmington Trust Co. v. Mutual Life Ins. Co., 177 F. 2d 404, the Court said: “A few months later while on a test flight in California in a glider piloted by a Colonel Gabel, duPont was forced to bail out and was killed when his parachute failed to open.” Webster’s New International Dictionary 2d Ed. defines the word “pilot”: “Aeronautics. One who flies, or is qualified to fly, a balloon, an airship, or an airplane.” See also 29 Am. Jur., Insurance, Sec. 968; Irwin v. Prudential Ins. Co. of America, 5 Fed. Supp. 382, (1934) U.S. Av. R. 77.

In our opinion, the language of the AviatioN Exclusion RideR is clear that the word “aircraft” therein used includes a single-seated glider, and there is no ambiguity in that respect.

In Provident Life & Acc. Ins. Co. v. Anderson, 166 F. 2d 492, the Court said: “Limitations as to war risks and aviation risks are often placed in the same section or clause of an insurance policy and the courts have been inclined to construe each type of limitation as if it were a separate and distinct provision. The mere circumstance that all the exclusions are placed in one sentence is not vital as long as no ambiguity is thereby created.”

In this RideR this risk is not assumed: “(a) If the insured . . . has any duties whatsoever aboard such aircraft while in flight.” The same words are used in the double indemnity provision of the policyThese words are plain, clear, and specific and create no ambiguity, nor do any other words used in the policy create any ambiguity in respect to these words.

“In the absence of statute, the ordinary rules of negligence and due care obtain with respect to the operation of aircraft. The degree of care required of one not carrying passengers for hire is ordinary care, that is, that degree of care which the great mass of men, or an ordinarily prudent or reasonably careful person, would use under the same or similar circumstances.” 6 Am. Jur., Aviation, Sec. 60. See also 2 C.J.S., Aerial Navigation, Sec. 19.

In Smith v. Metropolitan Life Ins. Co., 29 N.J. Super. (Appellate Division) 478, 102 A. 2d 797, the Court said: “Surely, if any one has ‘duties’ relating to an aircraft, its travel or flight, it is the licensed pilot thereof.”

“The law imposes upon every person who enters upon an active course of conduct the positive duty to exercise ordinary care to pro *449 tect others from harm, and calls a violation of that duty negligence.” Council v. Dickerson’s, Inc., 233 N.C. 472, 64 S.E. 2d 551.

A glider is not an inherently dangerous instrument on the ground, although in flight, when improperly used or improperly handled or in the hands of an incompetent pilot, it may be. It seems plain that the law imposed upon George Howard Scarboro the duty while piloting this glider in flight to exercise ordinary care to avoid injury to persons and property in the air and upon the ground, and particularly in returning to earth. Such being the law, upon the facts found by the Judge, the unfortunate death of George Howard Scarboro as a result of injuries received by him, when this glider piloted by him fell to earth, was not a risk assumed by the defendant, and the ruling of the Trial Judge was correct.

If the AviatioN Exclusion Rider had used the words, “If the Insured is a pilot, officer, and other member of the crew,” it might be that the word “other” would restrict the meaning of the word “pilot,” so as to mean a pilot who is a member of a crew. See City of St. Paul v. Traeger, 25 Minn. 248, 33 Am. Rep. 462, pp. 465-6. However, the RideR uses the words “or other member of the crew.” This creates no ambiguity. The risk is not assumed under the Rider if the insured is: (1) a pilot, (2) an officer, (3) or other member of the crew, or (4) has any duties whatsoever aboard such aircraft while in flight. George Howard Scarboro was pilot of a glider, whose fall to earth resulted in his fatal injuries. The specific words of the Aviation Exclusion Rider exclude his death from the risk assumed by defendant under the policy.

We have examined the case of Ezell v. Atlantic Life Ins. Co., 119 F. Supp. 614, strongly relied upon by plaintiff. In that case the language of the “Exclusion of Certain Aviation Risks” is not identical to the one here, and in the Ezell Case the two riders to the policies “were not as all inclusive as the double indemnity rider attached to each policy.” The Ezell Case is factually distinguishable.

A contract of insurance, like any other contract, is to be interpreted, and enforced according to the terms of the policy, and, unless such terms are ambiguous, they will be interpreted according to their usual, ordinary and commonly accepted meaning. Haneline v. Casket Co., 238 N.C. 127, 76 S.E. 2d 372; Johnson v. Casualty Co., 234 N.C. 25, 65 S.E. 2d 347.

It is our duty to construe policies of insurance as written, and not to rewrite them. Ford v. Insurance Co., 222 N.C. 154, 22 S.E. 2d 235.

The Aviation ExolusioN Rider states: “The provision of this policy relating to incontestability shall not be construed to require payment by the Company of any amount in excess of that provided in *450 this rider, if death of the Insured occurs under any of the circumstances set forth herein.”

Plaintiff makes no contention in her brief that the costs were improperly taxed.

The ruling below is

Affirmed.
