The EEL ULF 1 is a West German high-wing, single-seat, foot-launched, microlift glider that was designed by Dieter Reich.

When it was available it was provided in the form of plans by Entwicklung und Erprobung von Leichtflugzeugen (EEL) (English: Development and Testing of Light Aircraft) for amateur construction.

[1][2] The ULF 1 was first flown in November 1977 and first shown at the 3rd International Hang Glider Meet at the Wasserkuppe in August 1978.

Its two-piece, single-spar 10.4 m (34.1 ft) span wing is a cantilever design and employs a Wortmann FX 63-137 airfoil.

The pilot foot launches the aircraft suspending it on the shoulder harness and, once airborne sits on a retractable slat seat and closes two partial lower doors.
