Someone mentioned about flying a remote spy plane into A51...
I just wanted to post this so they get an answer as to why this has not happened (and cant)
They did mention about the frequencies so at least they realise that "they" can track back to you easily enough.
But the main problem is the range!
A good remote plane transmitter will have a range of about 500meters
a very good one will see you to perhaps 2.5km!
The distance from the perimeter fencing to anywhere interesting is about (from memory) abotu 15miles! (24km!)
To give you an idea the very best UAV used by the military,
The Predator UAV only has a workable range of 400nMiles (643km) and you wouldnt be able to use one of those.
The other downside is that a small plane (even if you had one that could do the range) could easily be shot down if its low enough to see anything.
And unless you decide to use a jet powered plane, it will take ages to get there
