define often? You would have to know how often they visit to say they crash often. What if they have been operating here for thousands of years and we have a crash or two. Would that be often?
Stealth? How do you know anything we have can track them very well? What if they have to let us track them, or there are certain operating modes where they are susceptible to radar and other times they are totally invisible.
Making any conclusions about why they would not be tracked or wouldn't is pure speculation and worse based on our own capabilities. 'Stealth' from radar might be incredibly easy for them.
- dogma1138 6y agoStealth doesn't work like you think it does, stealth doesn't makes aircraft invisible to radar, it makes them practically invisible to radar targeting systems as in it lowers and changes their RCS enough to not be considered an aircraft by the system that tracks them. And while their stealth tech might be much more advanced than ours, and provide true EMF absorption (as long as they have some sort of internal heatsinks because you can't break laws of thermodynamics) that tech wouldn't do you any good when you enter the earth's atmosphere you'll be lit like a christmas tree.
