Landing
Civilian aircraft are not supposed to land on the threshold (piano keys/numbers or whatever). They are supposed to cross it at 50ft, end off.
One reason military jets land accurately on the "spot" is that they don't care much about finesse (a 2g landing felt by one person is not the same as felt by 300 passengers!). There is also more limiting landing performance as alluded before, so they trade finesse for accuracy.
