Would you be referring to an African or European swallow?
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:Quote:

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.
Shamelessly googled from here... http://www.style.org/unladenswallow/
You were right - then all of a sudden you pull all those figures out your bottom. Although deviating from the original question in actual fact the maximum speed european sparrows can maintain is around 13–14 meters per second, and although the Lund study from Sweeden does not discuss cruising flight in particular, the most efficient flapping of 7 beats per second was observed at an airspeed in the range of 8–11 meters per second, with an amplitude of 90–100° - equating to 17–19 cm. Thus in pushing 43 beats you would be talking of another type of swallow, not euopean. If you were talking about one of the 40 odd species of African swallows them it would of course be a different story.
You were right before you started to get all technical :D (Plagiarised from unnamed sources.)

Did you just answer your own question https://www.ubeaut.biz/hehehe.gif

O.K. here's an easy one. What's the street address of the Simpsons' house?
742 Evergreen Terrace
What and where is this?
A big filter for my DC.
Where? I dont know I lost it.
Can you please return it?

standing in front of its launch support gantry is the first stage of a irish rocket booster engine shell on its side...
A reject from Federation Square (well, it is symetrical)
It's on the outskirts of a European city that has very strict requirements concerning the appearance of buildings constructed within it's limits. This building is in an area outside of that jurisdiction where anything goes and there are all sorts of weird looking buildings there.
Venise?

It's the 'Grand Arch' in la Defense, Paris.
Who wrote The Real Thing?
Rodney Marsh
russell morris wrote the song "the real thing"
assuming in correct heres the next quesiton :
"who was the assistant illinois enema bandit" ?

Sorry, Zed, but it wasn't Russell Morris. He sang it but it was written by someone else. Someone unlikely I might add.
Tonz, in Australia there is only one real thing ;)
Johnny Young.
Produced by Ian Meldrum
Yes!! I was starting to think I was making these too hard ;)
Well if we're going to talk about ancient Australian music :)
Miles Ago is the title of an album by which Australian band ?
Spectrum?
Yep.
Your turn
See how many of these you can get.
Who were the famous riders of these horses?
Bucephalos
Black Bess
Arion
Copenhagen
Marengo
Babieca
Incitatus
Pegasus
Trigger
White Surrey
Midnight
Bucephalos - Alexander the Great
Black Bess - Dick Turpin (highwayman)
Arion
Copenhagen - Duke of Wellington
Marengo - Napoleon Bonaparte
Babieca
Incitatus - Caligula (don't think he rode the horse but he had him made a senator!)
Pegasus
Trigger - Roy Rogers
White Surrey
Midnight
Struggling with the rest.

I knew Bucephalos and Trigger, so went googling for the others:
asking about Arion gave:
"Immortal Horses
Pegasus is perhaps the most familiar of Poseidon's equine offspring, but he is not the sole horse born of a unique union. Poseidon sires the horse Arion as well, one of several horses in Greek mythology to be endowed with immortality.
In other myths, Adrastus is not the sole master of Arion. Rather, the horse is first owned by Oncus. Herakles requests the horse for use in battle, and he then passes Arion into the hands of Adrastus."
Sheesh! Following on from just reading about the monk's spelling mistake (celibate for celebrate) makes me wonder if this bb is still family-rated.
I never knew until now that greek gods fathered horses.... my mind is still boggling. Did it happen every time? Did the poor mother know what she was about to give birth to? Did the midwife? Breastfeeding ? Nappy changing ?
Toilet training ? High chairs ?
Cheers,
Andrew
I think the lines between gods, humanity, and the animal kingdom were very blurred back then.
I nominate Driver as the next quiz master, seeing as he had most of them. All in favour?
Aye
Sounds fair enough...Quote:

OK
What was Tonto's real name (we're talking about the Lone Ranger's offsider, here, not our distinguished fellow member of this BB) and - apart from his fame as Kemo Sabay's mate, what else was he noted for?
Are you after the name of the actor who played Tonto?
Yes.Quote:

Well done, Tonz. Your go.
Ok an easy one.. What do these names all have in common?.....
Winnebago
Tobacco
Chinook
Laguna
Mobile
Mono
Yazoo
Well my guess would be that they are all the names of Native American tribes.
