Not so very long ago a small party of professors, Phd's, students etc.,
from
an English univerity made an expedition to Rio specifically to
investigate
this apparent revolution in the very foundation of Mathematics.

They returned with a new insight into how the human brain works with
numbers
and retired to study and then present their findings.

Since then all has been silence.

After they sobered up, they realized that the Brazilian Renaissance only
changed the course of world thinking for 12 minutes.

More likely, out of necessity, the investigators had to buy so many
cannabis-loaded cigarettes from sewer kids they returned from the expedition
as confirmed addicts.

Last I heard, there's no proof that cannabis is
physically addicting.

If you stretch a string on a globe from London to Florida, it will show
the 'great circle' route that's the shortest, and that should be your
plane's path, barring storme, hurricanes, etc. You'll see that it comes
really close to the eastern Canadian provinces.

In fact the Avalon Peninsuala in the most eastern part of the island portion
of the province of Newfoundland and Labrador, Canada, is a 'Way Point' for
many transatlantic flights headed to/from Europe.
Clear days Transatlantic flight con-trails, at 30,000 feet etc. can be seen
almost continuously.
That is why so many of the flights that were prevented from entering US air
space 9/11 had to land in eastern Canada.
Many US/Canada friendships were founded between grounded travellers that day
and eastern and western Canadians who voluntarily accommodated them during
the delay.
Cape Spear near St John's is the most easterly point in North America.
Marconi received the first transatlantic wireless telegraph signal near St
John's in Dec. 1901.
French is one of the 'Official Languages' in Canada. A significant
percentage of the population, mainly in Quebec, New Brunswick, but also
elsewhere in Canada, is French speaking. Many/most are bilingual.
Same way Spanish is significant in the USA?
The word 'Cajun' in southern US comes from the French word "Acadian";
originally inhabitants of Acadia or what is now the eastern Canadian
Province of Nova Scotia.
Terry.
PS. Staff at the National Historic Park at Signal Hill, St. John's, which
incorporates the memorial and events which celebrate Marconi's first
wireless telegraph reception say that visitors unaware of the approximately
1800 miles across the Atlantic, (4.3 hours by jet to London-Heathrow) will
sometimes ask "Can you see across to England/Ireland etc.". The answer is;
"No, but sometimes you can see "Whales"! :-)
And sometimes icebergs as well.

Any explanation for this?"

Fuselage of the airliner acts as a waveguide below cutoff frequency
(where diameter is at least 1/2-wavelength). Below cutoff, attenuation
soars rapidly.

FM wavelength is about 3 meters. AM wavelength is about 300 meters.
Propagation of FM inside the fuselage is OK. Propagation of AM inside
the fuselage vanishes quickly.

You need to stick the suction cups of your Zenith portable`s Wave Magnet
to a window to get AM reception.

Years ago I could get some shortwave reception by placing the
radio's whip antenna across the window and lowering the shade
to keep in place (and hide the radio). MW stations were generally
too weak to listen to. FM was a jumble at altitude.

These days RFI from the cabin entertainment systems completely
blanks out everything so don't bother trying. Be thankful MP3 players
still work.

With a window seat, FM works OK, especially (as has been said) with the
whip held close to the window. You can also get some SW reception. [I
remember listening to the BBC World service at 35,000 feet.] MW AM is
pretty useless (at those frequencies, the airframe is a Faraday cage).

Some airlines are/were OK about using radio receivers during the flight,
but I understand that these days, regardless of what the airline says,
you might get challenged by some 'over enthusiastic' security guy during
the normal departure security checks.

About 10 years ago (before the recent troubles), I did do some listening
on a UK-USA transatlantic flight. On approaching North America, I was
initially surprised that the first FM station I heard was
French-speaking (from Quebec, of course). I was relieved when I realised
that the 'driver' had not got lost.

One notes that you need to have permission from the plane's pilot to
operate any sort of radio (including a receiver) while in flight. With
receivers, the concern is with things like Local Oscillator or other
leakage signals.

Whether this is a legitimate concern is a topic of discussion (e.g.
they've flown commercial planes with an antenna and logging spectrum
analyzer in an overhead bin, and discovered that lots of folks forget to
turn off their cell phones), but the fact remains that the regulations
say no radios, except those permitted by the pilot in command.

And the reality is the pilot in command of commercial aircraft has to
follow the policies of his employer, most of which take the safe
route of banning everything that might even remotely cause a problem.

Well, about 10 years ago, Virgin Atlantic certainly did list radio
receivers as OK to use in flight (and I took advantage of the facility).
I'm sure that they would have been fully aware of possible technical
problems. However, the novelty soon wears off, and haven't bothered even
checking (or listening) since. In any case, the size and weight of your
carry-on bag has been severely curtailed (and such restrictions
enforced) and, on a 9 or 10 hour flight, you find that need to be more
circumspect about what you choose to pack in your cabin bag.
