Does plan have a short or long vowel?

Here's why:

* Short vowel sounds are typically quick and sharp. In "plan," the "a" makes a short, abrupt sound similar to the "a" in "cat."

* Long vowel sounds are typically drawn out and can be represented with a single vowel letter, a double vowel, or a vowel followed by a silent "e." The "a" in "plan" does not fit this description.
