Not much of the milk of human kindness in your veins, eh?
But a great deal of reality as people not belted are a hazard to themselves and others. On a recent flight at night, in the climb through a decaying area of convective activity, the seat belt sign was not turned off after take off though the cabin crew were gonged to start their duties.
Seated in an exit row on a 777, as soon as the crew in the seats facing us got up, the Frenchman next to me undid his belt. He was asked to refasten it, which he did. As soon as the crew disappeared he undid the belt again and hid it under his blanket.
A while later, in the cruise, we hit some moderate turbulence (overhead bins creaking, sideways and vertical motion, acceleration and deceleration). The seatbelt lights were flashed and gonged and the cabin crew came around to check belts (on departure the Captain had mentioned turbulence and asked for people to keep their seatbelts fastened - at least until the seatbelt lights went out and even then to keep them fastened - and the Purser had given BA's excellent briefing on seatbelt use whilst we were in the climb). The crew noticed one end of the Frenchman's belt hanging down from under his blanket and asked him to fasten it over his blanket - as had been mentioned by both the Captain and Purser. This he did but within minutes he released the belt and hid it in the folds of the blanket.
A few moments later one of the cabin crew came back and sat down opposite us and started to fill out somekind of form. We hit a particularly hard "rock" moving sideways and downwards and our friend's belt fell out of his blanket. When the crew member asked him to fasten the belt he made out he did not understand (though his previous conversations with the crew were in English). By gesturing and pointing at the sign the crew member had him fasten the belt again and helped him adjust his blanket.
Once away from the area of turbulence the seat belt sign went off and he undid the belt. Throughout the night he was regularly visited by a female passenger who sat on his knee and spent long periods kissing and stroking his face.
After some hours we hit a little light turbulence which, whilst not particularly causing unexpected motion, was persisitent. After a while the belt sign went on. The woman was sitting on the Frenchman's knee at the time and did not move, nor did he fasten his belt. She only returned to her seat under protest and he made another "I don't understand" pantomime about his belt.
Some people lose all common sense when they travel by air. It can be seen in behaviour at airports and on board. To not keep the belt fastened unless moving round and to ignore the fasten seatbelt sign is sheer stupidity. To do this in an exit row with over 4 feet of clear space in front and a greart deal of headroom is nothing short of moronic and, had our friend ended up damaged as a result of his behaviour I, for one, would have shed no tears.
