Note that this is actually a list, not a tuple as your subject suggests.
For the difference, take a look at this:
http://www.python.org/doc/faq/general.html#why-are-there-separate-tuple-and-list-data-types

Also, it's generally considered bad form to shadow built-in type names
like list.  This prevents you from using methods in the list scope and
makes for potentially confusing bugs.

This actually behaves as though you wrote this:
while (select != list[0]) or list[1] or list[2]:

The since list[1] always evaluates to a true value (non-empty strings
are true), the while loop body will always execute.  Fortunately, python
has a very simple way of doing what you want:

vehicles = ("airplane", "car", "boat")
select = vars
while select not in vehicles:
    select=raw_input("Wich vehicle?")
