How does a fly land on the ceiling?
- barrell roll ?
- internal loop ?
- other means ?
Эту проблему в первый раз в каком то motd на RH6 увидел, лет 7 назад, говорят есть секретные снимки, сделанные Natural History в 1958. А вот сегодня ответ нашел:
".... when they're going towards a surface, they literally have to throw themselves straight upwards towards the ceiling so their head points towards the thing they want to hit. They reach out with their front legs and they grab hold of something spiky or rough that they can latch these miniature grappling hooks onto. They then switch off and fold their wings away, and swing their body under them in order to lock onto the ceiling."
Ну а ползать там легко, присоски то, понятное дело, у всех волосатые есть.
