Think inclusion of the Harrier would be just about as absurd as the Dominie. Harrier GR7/9 may as well be a completely different aircraft so it's a pointless exercise. But then, the whole flypast is a pointless exercise. Surely, they should have just stuck to a Chinook and some Sea Kings? That's all it required. Alternatively, I can't work-out why they couldn't have combined it with the flypast for Her Maj the day before and just gone for a "25" formation from whatever type was available. It would have been a teensy bit more relevant and cheaper.
