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. I believe the evacuation problem has been solved. basically stairs analogous to the attic stairs to get to the top of the aircraft and then everyone walks off except for people near the front or back who h...Jump to post
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
I am disputing that CO2 is harming the environment; in fact my position is that the effects of more CO2 would be almost entirely beneficial. And I came to that conclusion by thinking and analyzing available evidence for myself, not outsourcing my thinking. But you have not yet answered my questions...Jump to post
No, the article isn't saying 1% passenger.

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.

In the 747 thread I've read that multiple 747-400 passenger frames are being used for military charters. I haven't seen any discussion or proposal for using retired A380s for similar purposes.

One other thing to keep in mind, both of the most promising vaccine candidates are mRNA vaccines.

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

It doesn’t in fact most airplanes can’t dump fuel. A big difference between MTOW and MLW would be a reason to include the ability to jettison fuel, right? Otherwise it's likely not needed.

Did they dump fuel on Bayonne and Jersey City?Jump to post
To be more accurate, ATC asked if they needed to HOLD for dumping fuel. The pilot's only answer to that question was "Negative". The question from ATC was ambiguous.
