Chopper asked why the earlier desert brown was mot used the second time around.
The reason is probably a different aim for concealment. The desert camouflage would work when there was a significant air threat. If no air threat then optimise your camouflage the next higher threat.
As for the false cockpit, the Vulcan too when it went to all over gave the same result. On the first Red Flag the aircraft had either anti-flash white or light grey. Near invisible until it banked when it flashed Here I Am.
With the new scheme you knew it was banking,but which way?
