Currently there are five ski flying hills, on which
World Cup events and Ski Flying World Championships
are held more or less regularly.
These five ski flying hills are: Oberstdorf (GER),
Planica (SLO), Bad Mitterndorf/Kulm (AUT), Harrachov
(CZE) and Vikersund (NOR).
And there's also a facility in the USA.
But the FIS certificate for the hill in Ironwood,
in the State of Michigan, already expired in 1995,
the hill is not used anymore, it's on the verge
of dilapidation.
Now the flying hill shall be turned into a large
hill. This means that jumps of up to 170 m will
not be possible anymore in the future, but the hill
in Ironwood would then be the world's biggest large
hill.
According to the wishes of the organizers, the first
competitions on the new hill shall already take
place in 2016. Plastic mats will be installed for
summer training and the carrying out of Grand Prix
events.
