How many are monoplanes and how many biplanes?
He would not tell us how many of the whole machines which had flown across country were biplanes and how many monoplanes.
That is perhaps illustrated by the change over from the biplane to the monoplane.
We continued to regard the slow biplane even as a fighter aircraft long after we should have adopted the monoplane types, as did other nations.
Further, an outline specification has been prepared in consultation with the operating companies for an all-metal, four-engined monoplane weighing about 40,000 lb.
The twenty-six aeroplanes mentioned include thirteen monoplanes of which only three have been delivered during the last three months.
We have, however, learned most useful lessons from these different types of airships and are now engaged in testing some of the more speedy monoplanes.
I suppose we have not more than two of these squadrons fitted with monoplanes.
