The only recent accident I can think of that occurred due to a mechanical/technical issue at cruise is AF447. Having two (and eventually 3) pilots in the cockpit didn't save that plane.Jump to post
If Tesla can turn their beta-version of full-self-driving-cars loose on public roads with a single driver monitoring their automation (despite obvious safety concerns), I don't see how this is much different. Except that an A350 at cruise has a much larger safety margin than a car on a crowded highw...Jump to post
Maybe the only way for them is to team up with an outsider, not one of the big two and work on some totally disruptive plane and engine combination. That’s risky and expensive. I assume you are implying they team up with Boom. Their military experience would certainly help them, even if Boom's spec...Jump to post

I was just reading up on the history of SSTs and I was intrigued about the testbed NASA used based on a re-engined Tu-144. They used Russian NK-321 engines that appear to have better performance specs (thrust and fuel consumption) than the Olympus engine that was powering Concorde. No way Boom uses ...Jump to post
The other was that the engines had to be optimised for a specific operating range and obviously it was cruise speed, but that came at a huge cost, because during take off and climb the engines were burning fuel like mad. That affects all aircraft. For each operating altitude and speed, there's some...Jump to post
Maybe now Boeing will just buy Boom and make the NSA an SST.Jump to post
West Coast to Hawaii would be awesome supersonic. 2 hr flight time arriving before you leave. If they can stretch the range a little bit, they could fly LAX -> HNL -> SYD. Logistically, this also makes sense for UA. Many of their hubs are coastal (EWR, SFO, IAH, GUM, IAD, LAX) and they could maximiz...Jump to post

So is the theory that the blade(s) went into the engine and then came back out the front (i.e. passed back through the fan) and sliced the cowling on the way out? How would it not damage other blades when passing back through the fan? I think the fan blade separated and was ejected forward, damagin...Jump to post
When you say cowlings do you include the intake ring? If so, no engine is ever run without an intake. Development engines do run with slave intakes during some tests but fan blade off tests have to be run with the production flight intake fitted. The cowling doors are not usually fitted for fan bla...Jump to post
On a new engine in development, this wouldn’t constitute a fan blade off test pass. I’m not sure how they will argue these engines are airworthy without a design change to the fan casing. A fan blade off needs to be a non-hazardous failure due to the frequency being above the allowable threshold fo...Jump to post
The BWB sticks to one deck (in any viable concept I've seen), but has concerns on evacuation.

This accident seems to have alot in common with the 2001 crash of AA587 that happened on climbout from JFK. The PCU/rudder hard-over issue has been fixed for decades. Is the rudder on the 737 large enough cause the separation or significant damage to the vertical stabilizer if given inappropriate pi...Jump to post
The whole series of AA training videos that posted yesterday was fascinating. This has all the hallmarks of a failure to recover from a critically-abnormal flight condition. Whether it was a rudder hard-over, failed flap or slat retraction, asymmetric thrust, STAB trim or stuck stabilizer, etc.Jump to post

Evergreen used McMinville Airport (KMMV) with a runway of 5420 ft to land the 747s that have on display at (or on top of) their museum. I’ve linked to a YouTube video of one of the landings below.
This whole idea that CO2 emissions are destroying the planet is a huge con. Consider: the historical range of CO2 concentrations extracted from ice cores is from 0.02% to 0.44%. The range that will support life is 0.017% to 5%. Below 0.017% plants die. Above 5% mammals die. The optimum level for pl...Jump to post
Everybody should know that military maneuvers are just burning money no matter how they do it - they're not producing goods or services for sale.

OP deserves more respect as if pundits here are not aware that airlines and industries uses normalized cabin for calculating CASM. What a shame!

Take note Delta this how you Handle an engine problem on Departure. It's wrong to equate the two situations. The AC 767 experienced an issue with a landing gear and an engine.

It's amazing how much people will pay to save 1hr on the LA freeways...the helicopter flight looks like it would have taken 30-45 minutes (if completed) and the time estimate for the drive at 9AM on Sunday (from Google Maps) is 1h 15m to 1h 45m.Jump to post
That is exactly my take. If the ASD-B is correct (and there really is no other data with no black box, unless radar turns up) he was climbing through the cloud deck (which he said he was doing in an ATC call moments before the crash) and lost control of the craft (stall?) or had a mechanical failur...Jump to post
