There is a plethora of reasons as to what’s going on with all the runway incursions and small plane crashes.
I know the airlines were effected by the COVID rule of no shot, no job, so the airlines were forced to hire whatever was available, including pilots that had been fired by other airlines. The ATC’s or Air Traffic Controllers are government jobs and because of that, they were also included in the “get the shot or get out” program.
Pilots are fired for any number of reasons, including not passing their check flight, which is a flight they are graded on by a Senior Captain sitting in the jump seat behind the Captain. Another reason to be fired is if they fail a drug or alcohol test, which is given randomly. As a pilot, I may show up at the airport for my flight and handed a specimen jar. That happened at least 3-4 times per year, sometimes back to back. Breaking the FAA rules or the airlines’ policies. Any sexist or homophobe language is also not acceptable. Of course, if too many pilots complain about another pilot using bad judgment. As a pilot, you must be an excellent aviator.
To me, there was no better job than flying. I always told my pilots that I was training to use the simulator as often as possible and practice for the unusual things that can pop up without warning like a blown engine or a stuck landing gear.
My opinion of small planes is that too many of those pilots want to rush through their training so they can get their license. Slower is better and many of them fail to study their manuals. These small planes are not allowed into certain areas around the airport. Mostly these are the areas where the big jets are taking off and-or landing. If I am 2 miles from the airport and I still need to descend 1500 feet to the landing strip, the last thing I need is to see a small Piper or Cessna in my zone. This has happened and forced me to do a go around, which costs the airline a lot of money due to the amount of fuel I will burn.
Runway incursions are caused by pilots not paying attention to their instructions if either going to the runway or going back to the terminal. I’m not sure what caused the one plane to clip the other one. I would venture to guess that either the pilot being pushed back didn’t have clearance to do so by the ground controller or the ground controller gave the pilot of the plane being pushed back bad instructions. Normally the Controller will say, “United 231 clear for pushback after the Delta clears you from behind.” If the person driving the tug begins to pushback too soo, there will be contact between the two planes. Both the pilot and the tug driver hears the instructions.
Right now, there are shortages of all kinds of jobs in aviation, including pilots, flight attendants, baggage handlers, gate agents and ground personnel.
I hoped this helped to explain “some” of the issues being faced at this time.
