JULY 14, 1921 IN PARLIAMENT •• •:•.. AirshipsREAR-ADMIRAL SUETER, on July 5, asked the Secretary of State for Air what is the Air Ministry's present policy with regard to developingrigid, semi-rigid and non-rigid airships, respectively ? Capt. Guest : I would refer the hon. and gallant member to the statementsmade in Committee on the. Air Estimates, ana to the public offer of airships and airship material to any organisation prepared to develop them forcommercial purposes. The policy, which is governed by the paramount ns-ed for economy, is, briefly, to discontinue the use and construction ofall types of airships ior fighting purposes, and to throw up existing material for disposal if no scheme of commercial use materialises by the end of thismonth. Rear-Admiral Sueter : Do the Admiralty agree with that policy ?Capt. Guest : I would refer the hon. member to the statement made in Committee on the Air Estimates." Lieut.-Com. Kenworthy : May we take it that the Air Ministry are not to be stampeded by a Rress agitation into reversing this decision ?Capt. Guest: No, sir. The Government have been slow in arriving at the decision, and they mean to adhere to it.Sir J. D. Rees : Will not the development of ships of varying degrees of rigidity lead to more and more expenditure ?Mr. Raper asked the Secretary of State for Air (i) what has happened to Zeppelin " L.64 " ? ; (2) what is the exact nature of the damage incurredby " R.36 " at Pulham, and how the same occurred ? Viscount Curzon asked the Secretary of State for Air whether any damagehas occurred to " R.36 " ; and if he can make any statement as to the cause ?Capt. Guest: The damage to " R.36 " consists of :— (1) A certain length of bow girder work crumpled.(2) A number of girders on the port side amidships broken. (3) A number of girders on the starboard side forward bent.The damage to the bow girder work occurred whilst landing the ship at the mooring mast, in the course of which, with the temporary winchgear in use, it was not possible to prevent the ship being brought up suddenly on the mooring wire. Such accidents are avoidable by the use of reversiblewinch gear, but, owing to the limitations both of time and money necessarily- imposed upon the present series of experiments, a cheaper form of windinggear was employed. Further damage occurred owing to certain guys carrying away when the ship was subsequently being housed. The hull of " L.64 "has been dismantled owing to the necessity of housing " R.^6" in the shed without delay. There was no empty shed at Pulnam when the accidentoccurred. A special inquiry is being* carried out into all the circumstances of the case. A report will be made, and I will send copies to the hon. andgallant members. Mr. Raper : Was " L.64 " fitted with nose tackle so that if her gas bagshad beeu inflated she could have been attached to the mooring mast instead of scrapped ?Capt. Guest: I do not think that " L.64 "—an ex-German ship—has ever been out of the shed since she was put in, owing to the fact that her nosetackle has never been in a proper condition. Viscount Curzon : Did the right hon. gentleman say what has happenedto " L.64 " ? Capt. Guest : Dismantled—another word for taken to pieces.Sir W. Davison : Will the comparatively small damage to " R.36" be made good, having regard to the splendid air-going capacity of that vessel ?Capt. Guest : The necessary repairs would involve six or seven weeks' work, and possibly an expenditure of from £4,000 to £6,000, and, in viewof the Government offer to close down all these matters, the Ministry did not feel inclined to proceed with the repairs. Mr. Raper : Are we to understand she is a complete wreck ?Capt. Guest : Yes, a complete wreck. Torpedo-carrying AircraftREAR-ADMIRAL SUETER asked the Secretary of State for Air what .progress is being made in det%ioping torpedo-carrying aircraft ?Capt. Guest : Steady progrtss is being made in the development of torpedo-carrying aircraft. It is obviously undesirable that details of thiswork, which is still in the experimental stage, should be published. Sir J. D. Rees : May I ask whether this, too, will not cost more and moremoney ? Ex-German AirshipsVISCOUNT CURZON asked the Secretary of State for Air on what date the ex-German airships allotted to this country under the Peace Treatywere surrendered ; and on how many occasions they have since been flown ? Capt. Guest: The ex-German airships " L.71 " and "L.64" were sur-rendered on June 25, 1920, and July 21, T920, respectively. Neither has beeu flown since surrender, as the gasbags were found on inspection to bedefective. Much valuable information has, however, been gained from a study of these craft. Mr. Hogge : How is it the hon. and gallant gentleman said a few momentsago that " L.6t " was a total wreck, seeing that we saw it in the shed a few months ago ?Capt. Guest : The hon. member did not listen to the answer. It had to be dismantled in the shed in order to make room for " R.36." PUBLICATIONS RECEIVED Year Book, 1921.
