DH was busy elsewhere those years, so it rather passed me by.
Good for the general public if it can be done - I take it your confidence in doing it again means that fire engines haven't changed much in the last decade!
Also, that training time can be fitted in: how long was needed last time?
I notice that the military was not used for the latest round of London strikes (that might be where I got the idea that the newest fire engines were too specialised without very lengthy training) - maybe too expensive?
