Launch aid support under the Civil Aviation Act 1949 for civil aircraft projects since 1950 includes:

TOTAL-£105.2 million (approx).The United Kingdom share of Concorde development costs totalled £574 million, and Concorde programme expenditure at Government research establishments totalled a further £76 million.Data on other research and development support since 1950 is not readily available, but support under the Science and Technology Act 1965 for civil aeronautical R & D for the period 1971–72 to 1981–82 has totalled £177 million, including £87 million on engines, £63 million on airframes and £27 million on avionics. It is not possible to break these figures down to individual aircraft.Further support for R & D will have been provided by British Aerospace when a statutory corporation, but details are not readily available.Data about R & D support to railway engines or ships is not readily available, but expenditure is thought to have been considerably lower than with aircraft.

asked Her Majesty's Government:Whether they propose to amend the financial provisions on divorce for Scotland on the lines recommended by the Scottish Law Commission.

The Scottish Law Commission's Report on Aliment and Financial Provision is being carefully considered by the Government with a view to legislation in due course. Their report raises a number of complex issues and it is not possible at this stage to say how far any legislation will follow the lines recommended by the commission.

asked Her Majesty's Government:How many prisoners were segregated for reasons of good order and discipline in Scottish prisons at the end of each month in 1981; what was the average number of prisoners so segregated in 1981, and what was the average population of Scottish prisons during that year.

The number of prisoners segregated for reasons of good order and discipline in Scottish adult prisons at the end of each month in 1981 was as follows:—

January	6
February	5
March	6
April	2
May	2
June	5
July	8
August	13
September	8
October	7
November	4
December	6

The average number of prisoners so segregated at the end of each month during 1981 was, therefore, 6. The average daily number of convicted adults in Scottish prisons during 1981 was 3,007.

asked Her Majesty's Government:When they expect to announce the outcome of their review of the Development Commission's work.
