Airbus steals Paris Air Show with twice as many new plane orders than Boeing

Published time: 21 Jun, 2019 15:32

European aerospace company Airbus has dominated Le Bourget airfield as it easily outpaced US rival Boeing with the number of orders for its aircraft on the final day of trading at the Paris Air Show.

The business program at one of the world’s largest aerospace-industry exhibitions closed on Thursday. Over the four days, Airbus secured firm orders, letters of intent and memorandums-of-understanding for 595 jets, while Boeing had orders for 234 planes, according to the aviation consulting firm IBA.iQ which tracks aircraft orders.

Boeing had a rough start from the very beginning of the show on Monday when the company recorded zero orders, while its main competitor in the large jet airliner market, Airbus, won 100 orders.

Boeing inked the first deal at the 2019 Paris Air Show on Tuesday, as South Korea’s biggest carrier Korean Air Lines Co Ltd announced the purchase of 20 Boeing 787-10s and a lease on 10 Boeing 787-9s. On Wednesday, it won its first orders for 200 Boeing 737 Max planes, a surprise since the aircraft were grounded in most parts of the world after two fatal crashes.

Orders at air shows are all PR. It's not like an impulse buy at

But if orders at the air show are just PR, why bother mentioning it?

And why exclude Airbus?

The British Airways order was announced at the air show, after Airbus had
run away with the market:

Airbus would probably do a great deal better if they could re-locate the
company someplace outside of the EU. As things stand at present, all
businesses are severely hampered by the EU's complex anti-business
legislation, which runs into millions of pages; thousands upon thousands
of impenetrable chunks of prolix verbiage (all resulting from the EU's
continual need to show the member states it's actually doing *something*
to justify its existence- even if that "something" has crippling economic
consequences for everyone).

(navvies) for workers and confiscating everything in sight would
be (has been, historically) a problem.

If you don't like the courts' decisions, that's a personal
problem, not California's.


I think they should design a contained (below ground) rail system
where the train is mag-lev and mag-motive, but has overhead
suspension (like the roller coasters) when failure or pause in the
meg-lev happens. That way, the tunnel can have banked turns
incorporated as well. Also, other utilties (DC links, etc.) can be
included in the Tunnel block.

Why would a long distance underground tunnel have turns?

To go between more than two cities? Seems like they're needed at
Albuquerque.

<https://www.youtube.com/watch?v=e8TUwHTfOOU>

Anything above ground is vulnerable and a waste of the space
required to be set aside for the run.

Fuck the scenic route shit. You want fast transport. Period!

I have no idea if such a tunnel is remotely practical. There is the Chunnel which must have been an ambitious project, breaking new ground <pun intended>. I expect an intercontinental tunnel would be a whole new ballgame though.

Musk likes the idea. It must be good.

There are reasons it would not be a straight run.

Having it that way would be nice. A plotted line averaged to lay
straight through the state best positioned such that the city-to-

mess.

Better to have the links between the cities as straight lines with
transitions at the city nodes to best point the line toward the next
stop.

Yes... there would be stops. Not much sense to have a train that
runs the length of the state and only be able to board it at the
endpoints.

I don't accept the hype about using superconductors for power
transmission anyway. It's not as if the existing transmission
infrastructure wastes that much, and the infrastructure required to
keep cables cool would be hugely expensive.

Seems to be a solution looking for a problem and one that would be
killed by economics.

Well the LASER was a solution looking for a problem, but it found them
in unexpected places. Instead of being a death ray or destroying
targets directly, they guide bombs, and also play music. But I thought
the expectations for HTS were small-scale, not the power grid.

I don't think you'll see many small-scale uses for HTSs until they
find one that's useful at LN2 temperatures. As mentioned here already,
"useful" includes current density.

Intercontinental, and particularly transoceanic would be virtually

Better off building a space elevator with a variable lift and release

There is no subway in DC. The submerged lines you refer to are
Trains, and they aren't subway trains. They trail into and out of
the city from other cities. ALL of DC's local transit is ground
based BUS lines. Contrast Boston or NYC or any city with real
subways and note they have turns. So do the DC trains, BTW.

Oh and wait, what you refer to is the TRAIN line DC has. I rode
it in to DC from Great Falls a number of times. A half hour ride
from Va over to the Capital, and come up to see the Washington
Monument in one direction and the Smithsonian in the other.
They have other lines from other cities.

A long haul, city to city jaunt line like that referred to in the
thread would have nodes at those cities and the entire line may well
have vector alterations at each node, since at each node, the train
must stop anyway. Not much between nodes, but it does happen.

It does not matter how deeply it is buried. The shallower the
better from a servicability POV. Much less in the event an
emergency egress is required.

What? Did you miss the "underground" part? It won't be 10 feet underground, it would be 100's of feet underground, well below surface obstacles.

What? The subway in DC is built with very few turns. The ones they have are purely to get the tracks in the right alignment for the station. That subway is only a few feet underground mostly. I think parts of it are more like running under the Potomac.

Sure there is a lot of regulation in the EU,
but it is not really anti-business, in fact EU was based on getting more trade between countries.
Sure politics makes idio^H^H^H^Hstrange decisions, but that is the case everywhere,
they outlawed pulse fishing (fishing using electric shocks)
while the Netherlands had invested a lot in it as it really works
and saves the environment(tm) and saves fuel and costs.
As to Airbus, they have factories in China and other countries:

For a large scale (>50 %) deployment of unreliable renewable sources
such as solar or wind, you either need

1.) Storage capacity for a day (solar) or a week (wind) consumption

2.) An energy transfer network, since unreliable sources are available
at different places at different times. An east-west power line around
the planet with power insertion and extraction at the continents would
be nice. A cable between Japan and Portugal would also be quite
helpful, especially with solar panels in Japan pointing eastward and
westward in Portugal. Current high voltage AC lines are economical to
about 1000 km transfer, DC links to a few thousand kilometers. HTS
would be required for truly continent wide networks.

Airbus doesn't seem to be remotely crippled. Boeing just had the 737-MAX disaster, which does suggest that the more-business-friendly environment in the
US is sub-optimal in stopping corner-cutting managers from killing passengers.

We do know where Cursitor doom gets his opinions from, and they aren't exactly independent sources - he sucks up right-wing propaganda and does seem to beleive it.

Underground tunnels go under rivers. They don't cross them.

The Channel Tunnel is a particularly obvious example.

Airlines work by having feeder routes into major centres, and longer distance links between those centres.

Railways work with non-stopping express trains between major centres and slower stopping trains to distributes the passengers to and from their homes to the major centres.

And, the success of the quicksort algorithm suggests that the scheme of short-long-longer
hops is a generally applicable principle. This has also been implemented in containerized cargo
haulage, big ships for long trips, rail for medium, tractor/trailer trucking for short hops.

It all works well, until some virus scrambles all your routing notes.
