Trans Atlantic flight, anybody?

A transatlantic flight was also a pipe dream for one of the founding
fathers of the French gliding federation, Raymond Siretta. He worked
as a pilot in French Guyana in the Thirties, and during his
transatlantic voyages (by steamer, sailing boat and zeppelin!), he
studied the skies and concluded it should be possible to cross the
Atlantic in pure soaring flight between Dakar (Senegal) and Cayenne
(French Guyana), 4000 km, using the trade winds.

This says that its northern edge is often marked by a line of clouds,
kicked off by the thermal edge between cold North Atlantic water and the
warm Gulf Stream. That made me wonder if the cloud street ever stretches
right across the Atlantic and, if it does, would it be strong enough
and persist long enough to allow a glider to make the crossing.

It would be a helluva flight!


Though glider flights across the North Pacific and
transcontinental glider flights across North America
are all but routine, I do think there has not yet been
one across the North Atlantic.

OK, I'll bite. Space shuttle glides, I presume?

Now _soaring_ flight, that's different.

PS.. What's the red shirt for, CV ordinanceman or StarTrek ensign?

So the blood doesn't show.

Some 40 or so years ago, John Fielden suggested that it might be feasable to
cross the Atlantic by dynamic soaring in the wind gradient associated with a
jet stream. I don't recall he had a theory on how one might find and remain
within that bit of air.

But his "copilot", Terry Delore, still is amongst us.
