OK... after weeks of trying to sort this out (and getting nowhere), I have to appeal for more help. Whatever I do, the plane, once manned, will then ignore everything (even a direct order to stop!) and taxi off at high speed until it bloes up or falls off a cliff.
I have tried:
Setting fuel to 0. As soon as fuel is set to 1 plane taxis off on it's own.
Setting myself as group leader, hitting preview, and immediately ordering the pilot to stop. This is ignored and he taxis off at speed.
Start with an empty plane, and order a group member to board as pilot. Once he is aboard... he taxis into the nearest forest.
planename stop false also sends him off on his own.
Even if the plane is perfectly straight on the runway, it will taxi off in some bizarre direction (usually south west on every island it seems!).
I am trying to make a 'destroy an airfield' mission. The idea is that all the planes start on the ground, and the pilots only board them and take off when the enemy (player) has been detected. Hopefully the crafty player could wipe out most of them before they get off the ground, but if you're too slow, you'll be into a dogfight.
Am I missing something really obvious (like a take off command or something)?
