I'm actually the last one to criticize a pilot in an emergency situation... especially when everybody is able to walk away from the aircraft after the incident... but in this case i've got to agree that was definitely one ****ty landing for a 120hrs pilot... even with all 3 wheels it would have been poorly executed.
Because the brakes work better when they're attached to a wheel. Coefficient of friction between rubber and concrete versus metal and concrete.
In a situation like this why would you use the brakes at all on a 2000m runway in a PA28...
