I've added a trajectory marker sub-model to the Canberra - I just used two line objects to form an inverted 'T' - seems to work well enough. I had to set the submodel <eda> to a very high value - just setting <speed> to zero wasn't sufficient as each marker object inherited the parent a/c speed, and so kept moving. Using a very high <eda> seems to stop it though and I haven't noticed any drift over a period of 15 minutes. While the markers indicate roll, they don't show pitch - I think this may be because of the high degree of 'air-braking' :) I've mapped the 'K' (shift-k) key to toggle the markers on and off.
