Airacobra Strikes

Military airmen seem to rest easier since announcement of the Airacobra, which they say actually does the 400 mph claimed for it. There's so much fudging and bragging and secrecy, the world around, about military planes that you don't know whether the speeds they tell about are diving or level, loaded or empty, in the air or on some designer's slide rule.
Army has been talking about 500 mph for a couple of years. Apparently it has no such animal on wings as yet. Nor has any other country, if the experts know their facts. They are glad about the Airacobra because they say it matches any fighter anybody has anywhere,
