asked the Parliamentary Secretary to the Ministry of Civil Aviation how many J. U. 52's have been converted to Jupiters; the total cost of conversion; and on what routes these machines are operating, or are to be operated.

Ten J.U. 52's have been converted to Jupiters at a cost of about £125,000. These aircraft are at present operated by British European Airways Corporation on five of their Scottish services, but are to be replaced in the autumn of this year.

Could my hon. Friend say, are all these ships being used at the present time; and on what specific routes are they being used?

These are aircraft, not ships. All the aircraft are being used. They are on the following services: Glasgow—Belfast; Prestwick—Belfast; Glasgow—Aberdeen—Orkney—Shetlands; Glasgow — Stornoway — Inverness; Glasgow — Inverness — Wick — Orkney Shetlands.

Could my hon. Friend explain why these aircraft, which are not by any standard modern, are used exclusively in Scotland?

Because, in fact, Scotland is getting most of England's air services.
