As far as I can tell, the FZ is more than good there. My biggest concerns were having a big obstruction moving through it and the RF being put out by both the aircraft and the airport. Before DHL pulled out they were landing a plane every 30 seconds starting around 10 pm and then they would take off every 30 seconds soon after. Went on all night until 6 or 7 am.
I know that all the systems aren't "supposed" to interfere with each other but that sometimes isn't the case. I have no fear of messing up their systems, they are certainly shielded to the good from outside issues but I don't have that luxury. But it sounds like no one has had any issues so we may at least test it out and see how it goes. This is the best path I've ever worked out, slam dunk as they say but there had to be a wild card in it. :) Thanks!

Unless the base of the runway is in the Fresnel zone... an airplane flying through it is only going to cause a minor interruption... maybe a few seconds?
