miss the boat/bus, to

To fail to take advantage of an opportunity; to arrive too late to profit. The analogy to missing a scheduled transport is fairly obvious and has been drawn since about 1900. One of its more curious uses was in a speech by Prime Minister Neville Chamberlain commenting (April 4, 1940) on Adolf Hitler’s invasion of Norway, “Hitler has missed the bus.” This was odd in view of Chamberlain’s own temporizing and attempts at pacification, which gave Hitler more time to embark unimpeded on his conquest of Europe.
