No. What I mean is: facilities have always been in place. Fewer have been crossing since a peak in 2010 if I remember right – and that was due to a different situation at that time. What has happened since what’s-his-face (not Trump but that other guy) announced zero tolerance? THAT’S when the crisis began.

Research Methodology. [I cleaned it up for better or worse] From: Farsi, M., Erkoyuncu, J. A., Steenstra, D., & Roy, R. (2019). A Modular Hybrid Simulation Framework for Complex Manufacturing System Design. Simulation Modelling Practice and Theory. I like this model. It looks standard yet it seems to capture all of the parts of doing good research, whether for aircraft engineering or your own. [They are all from “Through-life Engineering Services Centre, School of Aerospace, Transport and Manufacturing, Cranfield University, Cranfield,”]

measuring unit from which all else is derived. ——- The Planck length is the scale at which classical ideas about gravity and space-time cease to be valid, and quantum effects dominate. This is the ‘quantum of length’, the smallest measurement of length with any meaning. And roughly equal to 1.6 x 10-35 m or about 10-20 times the size of a proton. The Planck time is the time it would take a photon travelling at the speed of light to across a distance equal to the Planck length. This is the ‘quantum of time’, the smallest measurement of time that has any meaning, and is equal to 10-43 seconds. No smaller division of time has any meaning. With in the framework of the laws of physics as we understand them today, we can say only that the universe came into existence when it already had an age of 10-43 seconds.
