Craig,

How many Jump-capable ships are out ther in the 3I space?
Even a mis-jump will put a ship in a vicinity of SOME star system.
Are there still completely unsurveyed, uninhabited systems in 3I space which have no capability to detect starships in distress?

Here is a good servey of aircraft crash causes
Here is a list of aircraft where the crash site was never located

Considering overall the number of crashes, the sites never identified are very few, and mostly reflect the very small size of aircraft and their loss early in aviation history.
MH370

On a planet with 14 people per square including the water not even 100 years of plane travel and many satalites monitoring and mapping it all. 

"Let's fact check really quick. There are 7 billion people on earth, and the earth has a radius of 6400 km - which corresponds to a surface area of 5.1x1014 m2

This means there is about 0.028 square miles per person, so that's 0.073 square km per person. This is about 14 people per square kilometer. Of course, most of that area is water - if you account for the fact the oceans cover about 3/4 of the planet, this number is closer to the 48 figure you described.

Anyway, sqrt(0.073 km2) = 270 meters. So we'd each have a square plot 270 meters on a side if we were uniformly distributed over the earth's surface area. If we were uniformly distributed over earth's land, then there's about 1/4th as much area, so we each have a box about 135 meters on a side.

If you use a more accurate number for the world population or if you hold onto a few more decimal places for the radius/area, you can probably change this number by about 10%.": VeryLittle
