Gulfstream Delivers First Two G700s to Customers
Adapted from Chad Trautvetter
Gulfstream Aerospace has delivered the first two $75 million
G700s to customers, the Georgia-based aircraft manufacturer said
yesterday afternoon. Both are now in service with undisclosed
customers in the U.S. The company’s 7,750-nm flagship aircraft
received FAA approval on March 29, followed by production
certification and cabin interior approval on April 8.
“Beginning G700 customer deliveries less than one month
after achieving FAA type certification marks an incredible
milestone in Gulfstream’s history of raising the bar for the
business aviation industry,” said Gulfstream president Mark
Burns. “We look forward to continuing these deliveries in the
weeks ahead.”
Gulfstream had hoped for certification by the end of last year
and anticipated delivering as many as 15 before 2023 ended, but
the prolonged approval process has shifted those deliveries into
this year. As a result, Gulfstream anticipates a 44 percent bump in
deliveries this year to 160 jets, including 50 to 52 G700s and
fewer G280s due to the crisis in the Middle East.
Meanwhile, FlightSafety International has two level-D
simulators and three flight training devices for the G700 online at
its Savannah training center, with two more G700 sims under
construction. EASA and UK CAA conducted their final evaluations
of these devices two weeks ago. G700 pilot training started on
March 21, according to FlightSafety.

Global coral reef bleaching event underway as oceans get
warmer
The world’s oceans experience unprecedented rising
temperatures: last month, the average global sea surface
temperature reached a record 21° Celsius. Last week, the National
Oceanic and Atmospheric Administration (NOAA) reported the
4th global bleaching event on record. A press release stated,
“Within the last 14 months, significant coral bleaching has been
documented in the Northern and Southern Hemispheres of each
major ocean basin. Since 2023, the problem has become more
frequent in the Atlantic, Pacific and Indian oceans.”
According to NOAA, warmer ocean temperatures can result
in expulsion of algae that live in the coral tissue, leaving the coral
completely white - something known as ‘coral bleaching’. This
does not necessarily mean corals will die, as they can recover if
the strain on their ecosystems is reduced. At a local level, storms,
disease, sediments and changes in salinity can cause corals to
bleach. However, mass bleaching, which is when several varieties
of coral reefs are bleached, is largely caused by increased sea
temperatures. When these events are sufficiently severe or
prolonged, they can cause coral mortality, which hurts the people
who depend on the coral reefs for their livelihoods.
In 2019, NOAA published a study that provided “resiliencebased management practices” and __________ the importance of
coral restoration. “We are on the frontlines of coral reef research,
management and restoration, and are actively and aggressively
implementing the recommendations of the 2019 study.” A buoy
in Florida reported an ocean temperature of 38° Celsius in July
2023, according to meteorologists at the time. In response, NOAA
started a program to attempt to offset the effects of global
climate change on the local coral reefs by moving coral nurseries
to deeper, cooler waters and deploying sunshades to protect
corals in other areas.
