Good video! From an educational standpoint maybe emphasize the need to overshoot if you have not touched down by a certain point - maybe halfway on this runway with a slow stall speed - and how that varies.

For example, touching down 3/4 down an old SAC runway 12,000 feet long is fine in a 172, with no huge tailwind.

And this happens because of excess energy over the runway threshold- too high or too hot. Mostly too hot. Gotta get that airspeed under control.

Pretty sure that was an aztec... that did the overrun

The only thing that matters is the total energy the aircraft has, over the runway threshold,
which can be calculated as the sum of it's potential energy (height) and kinetic energy (speed),

Note that the height and speed of the aircraft 30 or 60 or 90 seconds before that instant
is completely unimportant. The system has no memory.

As we have discussed above, learning how to do a decelerating approach is very useful.



My groundspeed is well over 200 mph (with a headwind) in an elderly tube and fabric biplane
with no flaps so you guys in your modern metal and fancy new composite airplanes really ought
to be capable of approaches of 250 and 300 mph on short final.

Again, the only speed the matters is what you cross the runway threshold at. Doesn't matter
how you got there.

Upon closer inspection yup you're right that was a Aztec.
