^^^ Shouldn't that b a pic of bruce willis? You are showing the frail guy.

I had no issues with Josh and his staff. Other than they did not have enough time to get the job done.

I know I will regret this.

BUT can you, you personally, honestly say you have no problems with a guy who had a history of cheating caught cheating the exact same way again? You don't have a problem with a guy who was openly insubordinate with the owner?

King Arthur: So? We have ridden since the snows of winter covered this land, through the kingdom of Mercia, through...
1st soldier: Where'd you get the coconuts?
King Arthur: We found them.
1st soldier: Found them? In Mercia? The coconut's tropical!
King Arthur: What do you mean?
1st soldier: Well, this is a temperate zone
King Arthur: The swallow may fly south with the sun or the house martin or the plover may seek warmer climes in winter, yet these are not strangers to our land?
1st soldier: Are you suggesting coconuts migrate?
King Arthur: Not at all. They could be carried.
1st soldier: What? A swallow carrying a coconut?
King Arthur: It could grip it by the husk!
1st soldier: It's not a question of where he grips it! It's a simple question of weight ratios! A five ounce bird could not carry a one pound coconut.
King Arthur: Well, it doesn't matter. Will you go and tell your master that Arthur from the Court of Camelot is here?
1st soldier: Listen. In order to maintain air-speed velocity, a swallow needs to beat its wings forty-three times every second, right?
King Arthur: Please!
1st soldier: Am I right?

What if two swallows carried the coconut?

(Now I want to go watch this movie)

Guard: "An AFRICAN swallow, maybe, but not a European swallow. That's what I'm saying!"

Estimating the Airspeed Velocity of an Unladen Swallow
Hashing out the classic question with Strouhal numbers and simplified flight waveforms.
After spending some time last month trying to develop alternate graphic presentations for kinematic ratios in winged flight, I decided to try to answer one of the timeless questions of science: just what is the airspeed velocity of an unladen swallow?


What do you mean, an African or European Swallow?To begin with, I needed basic kinematic data on African and European swallow species.


South African Swallow
(Hirundo spilodera) European Swallow
(Hirundo rustica)
Although 47 of the 74 worldwide swallow species are found in Africa,1 only two species are named after the continent: the West African Swallow (Hirundo domicella) and the South African Swallow (Hirundo spilodera), also known as the South African Cave Swallow.

Since the range of the South African Swallow extends only as far north as Zaire,2 I felt fairly confident that this was the non-migratory African species referred to in previous discussions of the comparative and cooperative weight-bearing capabilities of African and European swallows.3

Kinematic data for both African species was difficult to find, but the Barn or European Swallow (Hirundo rustica) has been studied intensively, and kinematic data for that species was readily available.



It’s a simple question of weight ratiosA 54-year survey of 26,285 European Swallows captured and released by the Avian Demography Unit of the University of Capetown finds that the average adult European swallow has a wing length of 12.2 cm and a body mass of 20.3 grams.4

Because wing beat frequency and wing amplitude both scale with body mass,5 and flight kinematic data is available for at least 22 other bird species,6 it should be possible to estimate the frequency (f ) and amplitude (A) of the European Swallow by a comparison with similar species. With those two numbers, it will be possible to estimate airspeed (U).

In order to maintain airspeed velocity, a swallow needs to beat its wings forty-three times every second, right?Actually, wrong. By comparing the European Swallow with bird species of similar body mass, we can estimate that the swallow beats its wings 18 times a second with an amplitude of 18 cm:

Species Body mass Frequency Amplitude
Zebra Finch 13 g 27 Hz 11 cm
European Swallow 20 g ≈ 18 Hz? ≈ 18 cm?
Downy Woodpecker 27 g 14 Hz 29 cm
Budgerigar 34 g 14 Hz 15 cm

Note that even the tiny Zebra Finch flaps its wings no more than 27 times a second while cruising.

If we ignore body mass and look only at bird species with a similar wingspan, we can estimate an average frequency of 14 beats per second and an amplitude of 23 cm:

Species Wingspan Frequency Amplitude
Budgerigar 27 cm 14 Hz 15 cm
European Swallow ≈ 28–30 cm ≈ 14 Hz? ≈ 23 cm?
Downy Woodpecker 31 cm 14 Hz 29 cm
European Starling 35 cm 14 Hz 26 cm

By averaging all 6 values, we can estimate that an average European Swallow flies at cruising speed with a frequency of roughly 15 beats per second, and an amplitude of roughly 22 cm.

Tebow's going to prove people wrong. Haters are his motivators.
