I thought it was a valid and very interesting question.

My gut feeling is that if the system is done in C or C++ (for
example) it is going to have to use dynamic memory allocation.
Once you've taken that step, I don't think that Python is
inherently more likely to have memory problems, and I think
that Python is inherently _less_ likely to have many other
types of bugs.
If this were a simple, hard-realtime system with response time
requirements in the milliseconds, I'd stay away from Python,
away from C++, and away from dynamic memory allocation.
However, with response time requirements in the hundreds of
milliseconds and a problem domain that probably requires
dynamic memory allocation I think Python would be suitable.
The introspection features could be very useful for automated
testing, as could some simple instrumentation of the memory

Apparently Mr. Park thinks that ATC is a function of local
airports and they each build their own systems.
