Boeing changed their MO for the Dreamliner - they contracted out lots of aspects or the project, and the FAA stuff was certainly odd, according to people I know who worked for sub contractors on the project. They had expected it to be difficult, given all the totally new stuff and working practices, and how much had been rushed, but said it seemed to be a rubber stamp job.
I'm on a 777 tomorrow. Wish me luck!
Seriously, it isn't easy to avoid Boeing when traveling. Maybe if you have unlimited budget.
I would rather fly 777 than any other aircraft. No electronics upgrades please. The 777 had more tesing than any other I am told. I love the 777. My friend Colleen and I flew to Sri Lanka on A380 and 777. She was overcome by the A380 and I was bored by it. When we got in the 777 I said " This is a real aircraft ".
When someone pointed out that the Starfighter would outperform most modern aircraft if fitted with modern control systems a wave of fear went through suppliers. The Starfighter is cheap to make and effective. It required something better than a human to fly it as it's only downside. It had another problem. You had to read the manual on loading of the structure. People didn't.
No it was a grad student at MIT who interned at one of the contractors involved. It was sort of a morbid joke.
Holman Jenkins writing in this morning's (April 6) Wall St. Journal:
"A solution reportedly had been spelled out to pilots of the 707 and early 737 models but not pilots of later 737 models: Relax pressure on the control column briefly to free up the trim wheel. Repeat until the plane was back in trim.
If this account is accurate, it explains why an experienced Ethiopian Airlines pilot, who had been briefed on how to handle a failure of Boeing’s MCAS software after last year’s Lion Air crash, could not save his plane. In fact, he may have been reduced to turning the defective MCAS back on in hopes of freeing up the trim wheel."
Further on, Jenkins discusses the game theory going on between Boeing, Airbus to keep Bombardier from upsetting their duopoly.

You are welcome.. In my flying days I always made sure never to be the wind dummy...
That sounds wrong. I've done a search and the only thing I can see is that they originally used linked Ammo for the guns and the engines ingested the links so they went linkless.
Whilst we are on daft aircraft the lightning is an interesting one. Designed as an interceptor but by the time it had intercepted had to turn back as low on fuel. But the only plane that managed to catch concorde in trials.

They have two English Electric Lightnings flying at 'Thunder City' in Cape Town. The guy that's runs it (I think its still going) is Mike Beecher who is an ex SAAF pilot who went around buying up old combat aircraft. There's a few Mirages and some old Soviet planes as well.
The MOD refused him a license to fly the Lightings out of the UK - I think they went by ship. Anyway, for about $6k you can fly one (with an instructor of course) and you get to go supersonic 50 miles or so south of Cape Town.

Bullets are not light so consequently the speed of the bullets is added to the speed of the plane that is shooting them if watched from the ground.
Watched from the plane the bullets are simply a couple of thousand feet per second faster than the plane itself.
Bill is likely correct with regards to the links.
I remember one case where a jet fired its gun while climbing and then levelling out, and being hit by his own ammo at the ballistic return.
Must have been at least 30 years ago.

The top speed of Concorde was actually slightly higher than the Lightning by about 90km/h.
The Dassault Mirage (fighter and bomber versions) could outrun either by a couple of hundred km/h.
RAF didn't invite that one to play. I don't want to accuse them of loading the dice at all....
I know we regularly have to escort certain Russian planes out of airspace and I think it stops the typhoon pilots getting bored but in this age of accurate ground based missiles intercept capability seems an odd thing to worry about. But I don't have a military mindset.
I went to an airshow at mildenhall as a nipper which had all the 'loud' stuff there. Vulcan, starfighter, lightning. Generally the drill was take off, fly around a bit then low pass over the runway with reheat on.
Only time I have seen the red arrows take off, which is in itself very impressive as all 9 planes rotated and lifted off in sync.

They have one of the two X-29's at the cradle of aviation here. That is one awesome looking plane that I would never, ever want to be in when it flies.
Primarily because I have lots of experience with motion control software, and that plane requires it's software to keep the wings on the plane...
Software glitch, 5 milliseconds.....wings gone..
At least they didn't need a heartbeat monitor loop for safety, by the time it reacted, the pilot should already be out of the plane (if it is still possible to call it that by that time)
