After this it seemed too much to expect further inspiration. But a flight of Gladiators of No. 87 (F.) Squadron from Debden, Essex, supplied the impossible. For at least twenty minutes,
possibly longer, they performed tied together aerobatics that were sheer joy to watch. No matter what the manoeuvre, whether a dive on the clubhouse, an upward roll, or a half-roll off
a loop, the flagged cords linking the three together never varied their windstreamed curve; were never pulled taut, never in danger of being broken. A radio commentary by the leader added to the interest. Each time he was about to perform a new evolution he turned his operative "Go ! " into a sort of long-drawn-out war-whoop: F/O. G. H. J. Feeny (flight leader), P/O. R. L. Lorimer and Fit. Sgt. Dewdney were the pilots.
