During towed flight, particularly when the angle between the tow line jand the kite reaches, large values, kites can be exposed to very high load situations, sufficient tp result in structural failure. A commonly used device which exerts forces to hold the kite at a lower angle with respect to the tow line, is the climb restricting 'V bridle. Such a device was not used on this occasion. Recommended practice is for boat driver activities to be confined to steering while the observer is provided with a throttle control in a position which permits the Berson to face rearwards and be able to also operate the tow release. Should the observer detect a hazardous tow situation is developing he is able to assist by carefully reducing boat speed. The observer did not have access to a throttle control on this occasion.
