Unfortunately visitors to BZN (or Fairford) often see a number of 'white planes' and wonder why when their 'white plane' breaks they can't just jump on the 'white plane over there'.
Without going into the nitty gritty these 'white planes' come in several variants, of which only one type is capable of operating to certain operational airfields.
The remainder of the 'white planes' are not sufficiently equipped to do so or, as is quite often the case, broken.

Ironically,
Brize's flightline currently provides a very good visual of our 'spare' capacity...
