OK, let's suppose there are in fact 73 planes missing at the PNW. Let's ignore that quite often planes are blown to tiny bits when they collide with mountains, let's also ignore the fact that steep rock cliffs whom served as tombstones for Cessnas are not suitable for "bigfeet we know it, Jeff".
Now, remember that a viable (for a short term) population of bigfeet will need at least 50 breeding specimens. And for the population to be viable, these breeding animals must be living at an area where their territories have some overlap - otherwise they'll never breed. So, we are not talking about tens of specimens scattered across the PNW. We are talking about populations composed by more than 50 specimens (remember that you should add non-breeding individuals such as littlefeet), each one of these populations living at each "cluster" of bigfeet sightings. We are actually talking about tens of 2.5m-high apes concentrated at some areas -many of which are actually not far away from human infrastructure (towns, roads, farms, mines, oil fields, etc.) not to mention human hunting grounds- without producing a single piece of reliable evidence.
Despite of this, no bigfoot remains, no bigfoot turds, no DNA, no clear imagery, no good tracks (only fake-looking, inconclusive or misinterpreted stuff). Only sightings, blurry pictures, hoaxes and lame excuses for the absence of evidence.
Now, with this put, where's the relevance of the 73 planes which are claimed to be missing to the case in point again?
BTW, Makaya, I seem to recall you saying you thought they are extinct. Am I wrong or you changed your mind? If the second option is true, may I ask you why?
