'We did not purchase this thing so that it could play at being the home guard'
Err - yes we did - although, of course, it's not 'playing'. Air defence of the UK was always going to be a key role.
Don't try and shift the premise of your argument - you wrote that all Typhoon had done was to perform at airshows, and you were wrong. You might not value the QRA role, but it is one of the key military tasks placed on Defence and one which, I think, the 'taxpayer' is keen to see done properly.
We would all agree that Typhoon needs to deliver more, but your disingenuously abrasive style adds neither information nor amusment.
Have you considered adding an 's' to the end of your handle? That would give new readers an immediate idea of what to expect from your posts.
