Flying on Triton is no problem; you just need a chopper with blades a couple of kilometers long...
(Semi)seriously, would anything we think of as atmospheric flight work at all on Triton? I doubt that even a balloon "filled" with several cubic km of lab-quality vacuum would generate enough lift to get itself off the surface, much less a useful payload. Mars by comparison is a veritable pressure cooker. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

To conduct aerobraking at Mars - they used much of the instrumentation from other spacecraft ( or the actual spacecraft doing the braking ) to calculate the safe altitude to use. I would be more confident in a system that relied on in-situ density measurements from which to determine the best atmospheric path.

This is particularly true for Triton where there is some evidence that there is long term variability in its temperature and atmospheric parameters. You would end up with a very dead spacecraft if you tried aerocapture or aerobraking at Triton and weren't able to dynamically sense the in situ parameters of relevance (temperature\density profile by altitude) and respond to them on the fly so to speak.
