Progcomp 7

In the spirit of Faux preceeding me, this progcomp is gamelike; it's rather like moon-buggy for Linux. Given a strip of lunar terrain, you are to give instructions to a moon buggy driver to not crash.

• The moon buggy is 8 units wide, and the wheels are the first and last three units.
• The buggy has two controls: Jump ('j') or Forward ('f').
• Jumping moves forward exactly 11 spots; forward moves forward exactly 1.
• The buggy can drive over holes (represented by spaces) provided there is at least one bit of lunar surface under each wheel (surface is represented by underscores).
• However, the buggy can only safely land when each wheel touches two bits of surface.
• The buggy's wheels can never intersect rocks (hashes), though a rock can sit between the wheels.

Example

Suppose the problem is:

__________ __ ___ ##_______  _#_____  _ _ ________

Then we might solve it as follows:

__________ __ ___ ##_______  _#_____  _ _ ________
JUMP     ^^^^^^^^
LAND                ^^^^^^^^
__________ __ ___ ##_______  _#_____  _ _ ________
JUMP                  ^^^^^^^^
LAND                             ^^^^^^^^

The instructions fffffffffjffjffffffffff therefore form an answer. Notice that the two jumps here can't be moved without causing the buggy to crash!
