The cables only cover a small part of the angled flight deck.

The first cable is too close to the backof the ship for a safe landing.

After the aircraft touches down, the tail-hook bounces and may skip over part of the deck or the cables.

V0 = 42 ft/s

Va = 130 knots ≈ 40 ft/s

Vd = 700 ft/min ≈ 12 ft/s
