Professor Fitzgerald samples student power, running under tow across Trinity College Park, Dublin. Note the tow ropes going off to the right.

Fitzgerald, complete with top hat, displays his Lilienthal No 11 hang glider in Trinity College Park. The circular “prellbugel” or buffer hoop is well shown here.

The glider being flown as a kite, with the park railings terribly close by. This view portrays the radial wing ribs to advantage. Fitzgerald is the right-hand figure immediately beneath the glider. A student was lifted during these tests.

A rare airborne moment as Fitzgerald jumps from what appears to be a tilted table.
