What's the airspeed velocity of an inbound, laden Swallow?

Question

I'm looking for the answers for both the African Swallow and the European Swallow.

Answer 1

Can't answer that; we need to know much more information - what's the tail wind (or head-wind); what is the loading of the swallow (a cocoanut, a betel nut or perhaps a Holy Grail), and is the swallow being assisted by another swallow sharing the load on a length of creeper held under the dorsal guiding feathers. All these critical factors (and more) must be specified.
On the other hand, the universal answer would of course be 42 (I guess nautical miles per second in this case).
Take your pick.

Answer 2

It not a matter of where it grips it....its a simple matter of weight ration. A 5 ounce sparrow cannot carry a one pound coconut!
