From the article:

> The Swedish Saab Gripen C/D [...] was designed from the outset for ease of maintenance, and can be refuelled, re-armed and given basic maintenance by teams of just six ground crew using two vehicles on small airbases or highways, even in the harsh conditions of the northern winter. Moreover, only one of each crew needs to be a highly trained maintainer; the rest can be conscripts or even troops.

If this is true and the Gripen can achieve performances similar to other western fighter jets, I'm really wondering why maintenance of other planes is so much more complicated and costly or why the Gripen is not selling much better than it currently is.
