Tah 'orca' - good to know. The A-4 peeps will be familiar with the catapult hand grip, rotated sideways down (from UP position in flight) for grabbing on when throttle full forward for catapulting with throttle friction on full. This aid was an essential aid for the short A4G 100-110 foot cat on MELBOURNE at 5-6G.
One A4G sprog [not me] is reported as going down without the hand grip and no throttle friction. He recovered off the bow with - thankfully - the engine winding up again promptly. Extra cat energy was imparted for first A4G catapult, with aircraft at lightweight also from 'max. arrested landing weight only' fuel onboard.
