11—The Postmaster-General may make regulations with respect to the conveyance of postal packets in aircraft, and may for that purpose apply, with the necessary modifications, all or any of the enactments relating to mail ships and the conveyance of postal packets in ships.
Trespass and Damages for Injury Caused by Aircraft
12—(1) The flight of an aircraft over any land in the British Islands shall not in itself be deemed to be trespass, but nothing in this provision shall affect the rights and remedies of any person in respect of any injury to property or person caused by an aircraft, or by any person carried therein, and any injury caused by the assembly of persons upon the landing of an aircraft shall be deemed to be the natural and probable consequence of such landing.
(2) Where injury to property or person has been caused by an aircraft, the aircraft may be seized and detained until the owner thereof has given security to the satisfaction of a justice or an officer of police not below the rank of inspector to pay such damages as may be awarded in respect of the injury and any costs incidental to the proceedings.
Salvage of Wrecked Aircraft
13—(1) If any person finds, whether on land or at sea, an aircraft which has been wrecked or lost, he shall as soon as may be communicate with the police or other proper authority, and the police or authority shall communicate the information to the owner of the aircraft if he can be ascertained.
(2) Where any such aircraft is salved then—
(a) if the owner of the aircraft does not abandon his right to the aircraft he shall pay to any persons whose services have contributed to the salvage of the aircraft, including any person or authority who has given or communicated such information as aforesaid, any expenses incurred by them for the purpose and five per cent. of the value of aircraft as salved, after deducting from that amount the amount of the expenses of salvage payable by the owner, to be distributed among those persons in such manner as, in default of agreement, the Court having cognisance of the case may think just; and
(b) if the owner abandons his right to the aircraft, it shall be sold or otherwise dealt with for the benefit of the salvors.
(3) The Board of Trade may make regulations for the purpose of carrying this section into effect, and in particular may prescribe what authority shall be deemed the proper authority, the manner in which communications are to be made, the manner in which an owner may abandon his right to an aircraft, and the manner in which aircraft may be sold or otherwise dealt with for the benefit of the salvors.
