wow i must be really lucky, i get green stuff, white stuff, brown/tan stuff and black stuff
if your good at landing you will hit the green stuff that needs mowed most of the time,
if its summer and you miss the runway your plane will be saved by this amazing green stuff known as soybean, or a similir plane saving device known as wheat
if you really miss the runway your plane will be lost in this sea of greenstuff known as corn which is not fun trudging around in, however the plane will be just fine.

if its winter and you miss the runway the plane will be damaged and covered in this black stuff known as dirt or soil.

if that white stuff is on the ground its time to breakout the snowboard and not the planes.
i included pictures incase you dont know what corn, soybean ,wheat and dirt look like
that is not my plane in the first pic btw,
