If you didn't mind replacing the tires after every landing, and paying
for any runway lights you took out while skidding around, why not?

Perhaps we need to start modelling exploding tires.

Try bringing it across the (imaginary) fence at about 50-55 kt and 10
ft AGL with full flaps and idle power, then keep descending and
slowing by raising (yes, raising) the nose.  As soon as you're over
the threshold pull the nose right right up to the stall to plant the
mains firmly on the runway, then brake aggressively while holding full
back pressure on the elevators to keep the weight on the mains.

Ideally, you want to hear the stall horn just as the wheels touch the
runway, and you'll have under 40kt to kill off in the ground roll.  I
can manage about a 350 ft ground roll this way, stopping just at the
top of the runway numbers (not quite as impressive as Curt's
parking-brake-on landing, I'm afraid).

This is an excellent exercise for experimenting with the slow-flight
and stall envelopes.  You can actually feel for the stall by raising
the nose slightly then letting go -- if you raise the nose and the
plane climbs, you're still above the stall; if you raise the nose and
the plane descends, you're on the far side of the stall curve, and
raising the nose will help you descend faster (hopefully, you're only
a couple of feet up at this point).


All the best,


David
