Here's an excerpt from one of the articles I found.
"Flying at 300 miles per hour, Pardo carefully brought his plane's nose up under the rear end of the other plane to nudge his inch-thick glass windscreen against the tailhook. Any pushing had to be done with utmost care. If the glass broke, the tailhook would smash into Pardo's face. Pardo cautiously began to push his windscreen against Aman's tailhook for a few seconds at a time, in each instance just until the force of turbulence thrust his plane aside. Nonetheless, Aman's rate of descent began to slow.
Suddenly, cracks started to zigzag through Pardo's windscreen. Pardo immediately backed his fighter off and tried a different approach. This time he positioned the tailhook against the square of metal at the junction of his windscreen and his radome. Carefully, Pardo continued to push the other fighter a few seconds at a time, until turbulence would once again brush Pardo's plane aside. But the tactic was working. The rate of descent of Aman's F-4 was cut from 3,000 to 1,500 feet per minute."
