Hi Rod,
Yes I agree that it is not worthwhile showing routes for BOE flights and this one was allocated in 2012 when it was first picked up by the auto system as being flown. Unfortunately if we turned off the updating by the auto systems it could have other consequences and there is no way of updating some flight ID's and leaving others alone. This results in for example RCH flights showing a route where the system has determined its origin and departure points. Unfortunately unlike airlines, military, manufacturers test flights and business jets seldom allocated the same flight ID for a particular route and therefore the allocated route is usually wrong the next time it is flown.
I have deleted BOE246 however the next time it is flown the system may determine the route and then show it.
