We had one of my squadron's A-6 Intruder aircraft burn rubber down the #4 waist catapult after liberty call at JAX in 1975 aboard the JFK. The aircraft went below the deck then up a little, the BN and pilot punched out and the plane pancaked into the sea. A cold-cat launch. The pilot forgot to release the brakes! Both the pilot and BN went into the water, but OK. The pilot flew a desk for awhile after that.
