(Cl. 114-05) Landing sails for aircraft intended to be taken on board ship have hitherto been arranged at the stern of the ship. This arrangement is however not always desirable. In particular, if the arrangements for taking the aircraft on board and for projecting it were located amid-ship for example between funnels, the carrying of the aircraft from the stem to the centre of the ship would be avoided. This is achieved by the present inventachment and position of the two members extending from the point e are so arranged that this point e resists upwardly directed forces.

In the example of Figures -7 the spar d for the lower sail towing members 2 is laterally mounted 5 on the ship in the neighbourhood of the spar b for the upper towing members, for example beneath the same, and can be swung laterally and downwardly. It can be swung in against the side 1 tion, according to which the landing sail is maof the ship by a line 4, just as can the spar b nipulated by swingable and fixable lateral spars for the upper towing members by the line 5.
