  3.  Petition — contents.  Such petition shall allege all essential facts showing the necessity for bringing such action, the relief sought including proposed zoning regulations, and the necessity therefor.
  4.  Parties.  The parties defendant in such action shall be the municipality in which such airport hazard area is located, and all persons having an apparent or contingent interest in the property located within such area, who may be joined in said action generally as a class.
  5.  Procedure.  The action shall be triable in equity and in accordance with general rules of civil procedure, except that such action shall have precedence over any other business of the court except criminal cases, and the court shall set said petition for hearing not less than sixty days nor more than one hundred twenty days from the date it is filed with the clerk of said court.
  6.  Notice.  The original notice in such action shall be served upon the municipality in which such airport hazard area is located, and in the same manner as original notice of any other action but not less than thirty days prior to the date set for trial; and upon all other defendants by the publication of said notice in some newspaper or newspapers of general circulation within the area described in the petition, or as near thereto as possible, which publication shall be in the same manner as provided for the publication of other original notices, provided, however, that the last publication thereof shall be not less than thirty days prior to the date set for trial.
  7.  Decree and modification.  Upon trial the court may enter decree establishing such zoning regulations as it shall find reasonable and necessary. The court having once taken jurisdiction of such matter shall retain continuing jurisdiction thereof for such subsequent modification as it may deem advisable, upon proper application of interested parties, and due showing made thereunder after such notice to possible adverse parties as the court shall prescribe.
  8.  Appeal.  Any person or municipality adversely affected or aggrieved by any findings of the court may appeal therefrom as in other civil actions.
