There are procedures even at big airfields to deal with radio failure. For example, for one such field you head for a certain VRP, orbit 4 times to the right, head inbound and join downwind at 500' above pattern alt, head downwind and make one orbit, then come in for landing, while watching out for signals from the tower [or something like that, maybe I'll brush up on it
].
I think this pilot did the right thing, they walked away from the scene, only bending the plane. They obviously felt an urgent need to land for one reason or another, and so did, and survived. In hindsight I bet they can think of a hundred reasons why they f*cked up, but its all in the past, hopefully they learned from it and continue to fly.
My tip of the day is to know which circuit breaker is the electric trim, as these can sometimes run wild, and if it happens on approach you can be in big trouble...
