The ILA airfield
The meeting was held on an airfield on the grounds of the
Frankfurter Messe, around 3 km west of the centre of town. The
airfield was close to the Festhalle, where the 1909 ILA aviation
exhibition was held.
The exact layout of the race course is not known. It was stated to
have been 1,667 kilometres long, but the times recorded over the
course are unrealistically low, so it must have been shorter.
The airfield was only used during the 1909 meeting and was replaced
by nearby fields, first by the Griesheim military excercise grounds
two kilometres to the south and then from 1912 by the Rebstock field
two kilometres to the west.
Parts of the field are still used by the Frankfurter Messe, while
other parts have been developed for housing.
A map showing the 1909 ILA exhibition grounds and the airfield,
which was situated across the railway to the west. The Festhalle is
at the top of the map, and north is at around eight o'clock.
The "Flughügel" was an artificial hill for glider
flights. (1)

A rather murky photo, but it shows a light pylon at the left, the
ramp of the "Flughügel" and the grandstands to the right.
