Until the thirties airspeed was generally measured by a strut-mounted vane. This device was, as you can imagine, less than accurate and prone to huge position errors, but in a biplane with a stalling speed of 45kt and a VNE of 90kt this wasn't too much of a problem - anywhere in the middle would suffice for most purposes. Your 300 ton airliner is a different beast, sadly.
Little tube which pokes out of the aeroplane to determine how fast you're going. On the ground you put a little condom on it to stop waspies and so forth from entering the system. If you forget to remove said condom, you can't tell how fast you're going and soon enough, soankeroo will occur.
