Sometimes chains are a ‘good’ thing…
This plane captain is waiting for his bird to be spotted on the flight deck so he can chain it down.
The ONLY times a bird isn’t chained down on the deck or in the hangar is when they are being towed, or on deck if the pilot is in the jet and it’s getting ready to taxi or in the launch sequence.
Supposedly there is non-skid on the carrier decks, but by mid-cruise, it’s usually worn off to the point that the deck is getting slick. Add spilled oil, hydraulic fluid, etc. and it gets REALLY slick!
And with the noise on the flight deck during launch/recovery, you can’t hear anything. It’s even more ‘fun’ at night, when the only lights are red lights around the edges of the deck.
