Lack of plane has been easy on the ears these days.
Airplanes like trains in the past, you could say it was this or that. Now days other than a 747 (now retire due COVID-19) except cargo, 737 and dash 8, haven't a clue what they are unless I see the tail marking after shooting and checking the markings.
Taking the kids to the airport to plane watch was fun, and the 2 of us still do it when we can. Last year got to watch planes land and take off in Las Vegas in an area setup for plane watching. Had looked at other airports we would see on our trips, but none show where you could watch. Check a few out and came upon an area in Phoenix where we could park and watch. Wasn't sure about it until saw some cars parked there and it was at the east end of a runway and got to watch planes land, with an odd one taking off. Take off was on the other side runway. At Phoenix and Las Vegas, you see the planes touch down with smoke from the tires on touch down, but saw none from a number of planes.
Of the airports I visited in Europe to try to watch planes, Frankfurt was the best, as you could see them land, take off and taxi to/from a gate below you or near by. Got my first look at an Airbus 380 plane and airlines you don't see here. Wide range of planes. Even got to see where my plane loading gate was that I would be using a few days later to come home from. Something you can't do at Pearson unless taking a plane and only behind glass. Nice long out door viewing area.
