Have you ever heard the phrase?
I think people in aviation may be familiar with it. Perhaps it was coined during the 40's by pilots. It refers to the point in time and distance when it is no longer possible to abort a take-off as the Jumbo or the Airbus trundles down the run-way. Beyond the PNR, it would be impossible to bring the aircraft to a stop, even if there is an engine failure, and it must continue and attempt to be airborne, whatever the consequences.
Perhaps this happens in many human lives too. A sequence of events, one leading to another, and before you know it, you are at the PNR!
Have you ever had a PNR in your life? Perhaps marriage is one such event as you take those vows. You know that there will probably be no turning back. You can move forward, but never back.
Or your decision to embark on a certain profession.
In the lives of countries too, a PNR is reached. Certain policies can have far reaching implications, decades later.
Do you think perhaps it would be a good idea to watch out for the PNR in an individual life, or the life of a Nation? Whatever corrective measures maybe required can be taken before you reach the PNR! Beyond that you carry on! Regardless.
