Hello

Peregrines are tremendously amazing, terrific, brave and mainly beautiful, both perched in flight.

However, the publication we see above by National Geographic is an absurde and erronious desecration of some soo pure and beautiful as are Mathematics and Phisics.

Actually, after the video we do not nothing about the experience... to start it should not be anything near of tyhe Peregrine if we want measure its air speed, otherwise for example the drag caused by the lure will pulled ahead the falcon and it get more speed; Worst if there are people falling below the falcon.

In my opinion, what increases the parasite drag in the Peregrine body, in such a way that the Peregrine terminal speed (150 or 200km/h) is well above theoretical values for 'ideal' falcons (about 500km/h), is the fact that the feathers of the falcon are not stable a such high speeds.

(!!!And still the question: What does the computer do?)
