Harold Graham and a support crew travelled to many cities in the USA. They visited Canada, Mexico, Argentina, Germany, and France, as well as other countries. Each time they successfully demonstrated the rocket pack in action before the public. However, the army was disappointed. The maximum duration of flight of the rocket pack was 21 seconds, with a range of only 120 m. A large contingent of service personnel needed to accompany the rocket pack. During flight 5 U.S. gallons (19 liters) of hydrogen peroxide was expended. In the opinion of the military, the "Bell Rocket Belt" was more a spectacular toy than an effective means of transport. The army spent $150,000 on the Bell Aerosystems contract. Bell spent an additional $50,000. The army refused any further expenditure on the SRLD program, and the contract was cancelled.
