Test pilot/commercial astronaut who’s Forest Gumped his way through an amazing aerospace piloting career. Didn’t write “Test Gods”, just takes the blame ;)
I’m on X for two main reasons - 1) to give unique insight into aerospace topics garnered from my unusually broad test pilot career. 2) To inject humor (usually sarcastic and sophomoric at best) in the hopes of getting at least one person to smile.

Yes, I took the video but I don’t want it shared on
@Fox
because I don’t want a simple factual video to somehow be associated with heavily biased news.
NASA wanted a close chase of the X-38 in gliding flight to calibrate the air data system. I used an F-16 with 3 empty fuel tanks for maximum drag. I also had the landing gear down, speed brakes out, & used full rudder and opposite aileron up to the few seconds of data collection.
During my military and NASA flying days I never scheduled a photographer for me. Not once. Over a quarter of a century after the fact, I just got sent this photo of me taxiing out in the very cool F-16XL with an even cooler SR-71 in wait.
Saddened to hear of the passing of Soviet test pilot Anatoly Kvocher at age 72. He gained international recognition in the late ‘80s for his impressive MiG-29 flight demonstrations, one of which culminated in a very last-second ejection at the 1989 Paris Air Show due to a bird
I don’t normally post work stuff but it was great day for New Space in New Mexico Space! The team at Gateway to Space, Eve, and Unity knocked it out of the park today!
One day when I was flying a F/A-18 proficiency sortie at NASA-Dryden, I noticed the winds were over 150 kts so I turned directly into them & slowed down until my ground speed showed zero. After a few minutes of it, ATC finally asked me what I was flying.
I replied, “an F-18.”
These days it’s extremely unlikely to inadvertently land on the wrong aircraft carrier but it was once a thing. I remember when an F-14 that was based on a nuclear carrier landed on a diesel carrier! The “gaining ship” always returns the bounty but only after a bit of rebranding.
@SciGuySpace
@nickschmidle
The most misleading statement today was
@virgingalactic
’s. The facts are the pilots failed to trim to achieve the proper pitch rate, the winds were well within limits, they did nothing of substance to address the trajectory error, & entered Class A airspace without authorization.
Even after

following

, there continues to be a huge disconnect between company statements & my take on what went wrong, why, & the pilots’ failures to follow procedures & take appropriate actions. Time for an independent review?
That’s true, the boosters launched separately, retracted their legs, burned for a few seconds and then coasted upwards, eventually joining with the center core in space.

This 9/11 photo by Robert Clark really captures the horror of the moment of realization that our nation was under attack. The anniversary brings weird emotions to me. I was a newly trained United B-767 pilot that was scheduled to fly that flight on 9/18. I eventually lost my job

For some reason I was selected as a NASA astronaut finalist while I was still a TPS student. In the big board interview, John asked me “as a test pilot, I’d like you to critically compare for us the flying qualities of the F-18 to the F-4.”
Today we honor the legacy of astronaut John Young on his birthday.
John completed test pilot training in 1959 and worked on Crusader and Phantom fighter jets in the US Navy. He also set the world time-to-climb records to 3,000-meter and 25,000-meter altitudes in the Phantom.

You could eject from an SR-71 at design mission speed of M3.2 because dynamic pressure is normally a bigger constraint for surviving aircraft ejection. It would be a heck of a thermal problem but you could design an ejection system that would be survivable to orbital Mach.
When Maverick ejected at Mach 10.5, he was going 7,000 mph, giving him 400 million joules of kinetic energy — the explosive power of 100 kg of TNT. A situation that human physiology is not designed to survive.
So, no. Maverick does not walk away from this. He be dead. Very dead.
There is a lot of dark/dry/harsh humor in the fighter pilot biz. Two years ago I earned my commercial astronaut wings with

I once did a talk at the NYC Explorer’s Club and there were some

customers in attendance and one said that he had been to almost all the countries in the world and he wanted to fly on SS2 so he could see them all at once. I gave a tight-lipped head nod.

It seems all the artist conceptions of balloons that claim a space or need-space experience show views from altitudes that are well beyond low earth orbit. I’m enclosing a Google Earth view from a more realistic altitude.
Yesterday was the 11th anniversary of the first powered flight of SS2 Enterprise (myself and Mike Alsbury). We had Brian Binnie fly Proteus up ahead of us and ~800 ft lower in altitude. Photo by Michael Fuchs.
Well since the post about flying slow in a standard F/A-18 seemed to resonate, I guess I’ll mention that at the time I also flew the thrust vectoring F-18 HARV. The bottom line is once you’ve tasted thrust vectoring you never want to go back to a standard fighter. You could sit

Probably the hardest thing about faking an Apollo moon landing would be figuring out where to hide all the hardware (that tens of thousands of spectators saw launch before their eyes) from the Soviets and Chinese who would have loved nothing more than to expose us if we cheated.

After failing to trim down in the vertical [I have an excuse!!!] the nose pitched beyond the vertical & I got a GLIDE CONE caution as we accelerated away from the field. So I did a 180 roll and flew inverted to fix the caution & drive the reentry point directly over MHV. Whew!
Primary objective: airspeed comparison (fly abeam, co-altitude, two wingspans of separation for as long as possible)
Biggest challenge: X-38 has a glide much worse than any chase plane, is released below stall speed, and accelerates quickly.
Since I was around 30,000 feet altitude, this meant my indicated airspeed was around 90 knots. It was achievable but I was in full afterburner and in an elevator going down!
Be careful what you brief and who you trust in your backseat! Can’t remember if you pulled the ejection seat handle? You’ve gotta be kidding me! If they recover the seats it should be pretty easy to prove who pulled it!

@Astro2fish
for flying mini’s name tag to space.
Why do aerospace companies use “anomaly” for what the average person would call an explosion, crash, loss of vehicle-type event? It’s a euphemism that I feel alienates those they are hoping to placate. Whether facts or rumor, the truth will come out & up front candor is best.
Regarding last week’s Centaur V anomaly, here’s a photo of the resulting explosion at Marshall Space Flight Center. Good luck to ULA on its investigation and getting the Vulcan Cert-1 mission off the ground.
Incredible that
@blueorigin
*and* the astronauts agreed to release full video & audio of the entire flight from crew-up to landing. Certainly something that you won’t see from a certain other company’s last suborbital flight ;)

One of the things I pushed for
@virgingalactic
was electronic polling for the various commit points in the mission timeline. Even though it has years of heritage “go” and “no go” seem like an invitation for a simple clipped transmission to become a critical link in an accident.
So my big remaining question about Firefly’s launch is whether the half assed ‘abort’ heard over the loop was relevant to the engine failure, or something else. Was it unrelated, or did we misunderstand.
The operating costof the Blackbird also included the 3 tankers used for operational missions, one that went to the assigned route, the other two that went to decoy routes.
Reading SR-71 operating cost estimates from the late 1980s that range from $160k to $200k PER HOUR.
That would place it at around a half a million dollars per hour to fly, when adjusted to today’s inflation.
I’ve said it before and I’ll say it again: the Cold War was crazy.

FSD but I have a very close friend who realized something was very wrong & used FSD to drive home before dialing 911. Thankfully no permanent damage from the mini-stroke.
My rule of thumb is to always strive to leave yourself *two* ways out. This appears to be horrendously violated by:
1. Flying at full power while pushing the glider for max aerodynamic speed (highest risk of collapse) without hands on the controls to deal with such an event.
2.

We always here about how bad the methane in cow farts is for global warming. Don’t your engines run on methane? Aren’t there a lot of cows in Texas?
The NASA F-15 ACTIVE was certainly impressive. I remember chasing it through a MIL power 5g turn test point at 30,000 feet. I was in full afterburner in a F/A-18 and it left me in the dust.
Adding canards and vectored thrust to the F-15 massively reduced take-off roll and the length of runway needed to land - so it could be used from very short strips and damaged airfields. Should it have gone into production do you think?
A very insidious cycle. More thrust = more propellants. Where? New tanks or CTN means a new qual program. Very hard to get one or two custom tanks. More weight? Oops, beefier brakes & landing gear. Wing now needs reinforcements. Now even heavier — needs even more thrust! 1/3
