large airport route

hi all
a while ago I downloaded a large airport route.
Deleted it now I cant find it on the DLS
It had helicopters planes etc
The planes took off from a base boards miles away
The invisible track was placed on one base board then a large gap to the next and so on till reaching the airport
so you could not see the ground
anyone no what it was called

hope this makes sense

hi think I've found it its heathrow downloading it now to check
:hehe:

That is my route indeed and yes it is Heathrow. I have been working on the proposed third runway which may or may not happen for real. Planes now have a choice of three landing and take-off runways.

Thanks I am trying to make an air base for USAFE planes and am using your route for inspiration.
Your route has so much to use.
Brilliant

Matt
