GOLF BRAVO ZULU.
Not wishing to be pedantic, but Red 1 went MID - IBY - ORTAC.
The MID - ORTAC route was introduced later with a base of FL105.
Traffic flying below FL 110 was forced to go the long way round via IBY or leave controlled airspace and request rejoin south west of MID or north east of ORTAC depending on their direction of flight.
Happy days !!!
