  OPINION OF THE COURT
  PER CURIAM.
  This is an appeal by a bankrupt corporation from an order of the district court confirming an order in which the referee had confirmed the sale of the bankrupt’s corporate trade name and the bankrupt’s revoked certificate to operate as a supplemental air carrier to a purchaser for $5,000.
  It is not contended that the sale price was inadequate. All of the tangible assets of the bankrupt had been sold before the presently challenged sale.
  In dismissing the bankrupt’s petition for review, the district court reasoned that:
  “[u]nder Section 39c of the Bankruptcy Act, only a ‘person aggrieved’ can petition for review of a Referee’s order. A ‘Person Aggrieved’ is one who is directly and adversely affected pecuniarily by the order. Hartman Corp. of America v. United States, 304 F.2d 429 (8 Cir. 1962); In re Henry Wood Sons Co., 279 Fed. 608 (D.C. Mass.1922). In any event, real value was realized by the trustee for the benefit of the creditors, and the bankrupt may not petition for review where fair value is exchanged for the asset, if it be one, of only a skeletal charter and a dormant right of purchase. Of course, a grossly inadequate bid is quite another matter. The argument of the petitioner is that the trustee had no assets to sell in this regard. If that is so, then only the purchaser has been harmed by his speculation. If the bankrupt corporation had inherent rights in these intangible property rights, then the trustee’s duty under the Act was to sell, and this is precisely what he did.”
  We agree with the district court that the bankrupt was not “aggrieved,” within the meaning of the Bankruptcy Act, by the sale it is attempting to challenge.
  The judgment will be 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 "transportation". Your task is to determine what subcategory of business best describes this litigant.
