Well if drone can fly by battery power why can't planes eventually run
on batteries.

They already can. Just not for very long

Solar Impulse 2, did OK


You do know why it flew in the direction it did? You won't
see a return journey from it. Hot air balloons did it
quicker with more passengers.

You do know why planes follow the routes they do don't you ?


Do you think the solar plane followed the same routes as the
airliners?

No, but do you actually know why aircraft tend to follow the same
'path' ?


Some crashes in the '50s. Why do you think they do?

I don;t think I kknow.

There was a program on it a week or so ago.

The reason is radar. ONly 10% of teh earth has radar coverage and
it;s risky lettign a plane go off radar as yuo don;t know where it
will be and can't predict it's exact course, so planes were told to
follow routes.

They were allocated routes after some crashes as they didn't follow
routes and flew by eye.

So they didnlt know where the planes were at a specific time because they weren't on radar.


That meant that more than one plane could be travelling in the area at
the same altitude and different directions.

So why was that a problem ?

They then assigned routes to keep them apart.

exactly.


Radar had nothing to do with it.

It had everything to do with it.



Now with more planes havign GPS and with the increased number of GPS
satellites it has now become possible to use just GPS and not rely on
radar, so now planes can travel across the centre of oceans and still
be tracked. The london city airport is rolling out it;s new system,
so you can be in the controll tower anywhere in the world as it's
just a roon with lots of large 4K screesn that take teh place of
windows, yuo can zoon right in on the plane even more so than
prevuious using binoculars to see the planes coming in. This will or
so they think will enable them to fly more planes as theere can be
more routes.


Totally wrong.

Not according to those that know about such things.
