Wow, I'm impressed:

"The flight performance test aircraft has achieved a maximum speed of Mach 0.995 and an altitude of 53,000 feet."

"The G500 is designed to provide its customers with a range of 3,800 nm at Mach 0.90 and 5,000 nm at Mach 0.85."

Looks to be a worthy successor to the venerable G-IV. I still cast a prejudiced view at a lot of the new technology, even after spending some time with a 650, but I hope it works out. The G-IV is still a great airplane, but it's gotten long in the tooth at this point.
 
I can still remember in the late 80s, when the G-II/III were still king and the G-IV was coming on line to assume that crown.

Me too, I was working line service at KBUR and can remember the first time I went into the cockpit of one of GACs (Warner Bros.) G-IVs to talk to the crew. It was like I was seeing the "future", and in hindsight it really was.
 
I can't keep track of all the Gs. I think I'll just group them all as GIVs as it goes streaking past me.
 
As a mechanic I will say I've never gotten better support from a manufacturer than Gulfstream, sometimes it's hit or miss regarding who you get when you call tech ops, but they will find someone that knows how the striker arms on a G-II are supposed to be adjusted if that's why you're calling.

Will trigger the little used reg that one pilot must don space suit if one leaves the cockpit.

Damn near,

according to this calculator, and this calculator water boils at 47C at FL530 on a standard day... That's...interesting...

This is cool too: https://en.wikipedia.org/wiki/Clausius–Clapeyron_relation
As is this:https://en.wikipedia.org/wiki/Boiling_point

If you figure out what the pressure is at FL530 (spoiler alert, it's about 100mb) and follow along on this chart. You can see the calculators are about right. Coffee is supposed to be served at around 70C, so if you blow a window out of this thing, you'll definitely not be able to drink your coffee, because it'll be vapor.

It'll go down something like this, " (pshewwwww) what was tha?... "

Then the comment " they died doing what they loved "
:)
 
Supposedly the replacement for the USAFs EC-130H Compass Call communications jammer planes, is to be a version of the G550.

it's a lot easier in turbine airplanes to spill your coffee than you'd think.

Especially with the cup holders in the 747. Reach your right arm straight out to the 3 o'clock position. Now move it back to the 4:30 position and then reach back about a foot. That's where the FO cup holder is. Boeing has chosen to have frequent spills with hardly any consequences vs handing stuff across the center console.
