  Sitting by designation pursuant to 28 U.S.C. § 292(a).
  Opinion PER CURIAM.
  PER CURIAM:
  The petitioner and appellants in these cases contend that the Washington Metropolitan Area Transit Commission lacked jurisdiction to regulate their activities. The thesis underlying this claim is that the Commission is empowered to regulate only “transportation,” and the petitioners’ and appellants’ primary business is “sightseeing.” Although their sightseeing business involves transportation for hire, the petitioner and appellants argue that this transportation is only incidental to the sightseeing and so is not reachable by the Commission under the powers granted it by Congress.
  Many cases of this Court have implicitly recognized that transportation operations which are tied to sightseeing operations are subject to the jurisdiction of the WMATC. See, e.g., Holiday Tours v. WMATC, 352 F.2d 672 (D.C.Cir.1965). Nothing in the law strips the WMATC of its jurisdiction simply because those providing transportation for hire are also in another business; the law looks only to whether transportation for hire is involved. Washington Metropolitan Area Transit Regulation Compact, D.C.Code § 1-2411 (1981 Ed.). The WMATC thus had jurisdiction in this case.
  The other contentions of the petitioner and appellants are also without merit. For the foregoing reasons, the district court and WMATC decisions under challenge here are
  Affirmed.
instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 
  
  Your task concerns the first listed appellant. The nature of this litigant falls into the category "private business (including criminal enterprises)", specifically "other". Your task is to determine what subcategory of business best describes this litigant.
