Work on the ramp can be pretty lame, but I get to see 757s every day.

IMHO, the 757 is the Constellation of our age. Beautiful aircraft.

The Thunderbird pilot swatting at debris floating in the cockpit while doing an 8 point roll is *awesome*.

These just get more and more terrifying. It's bad enough that one of them sounds like a swarm of flies all on its own. Then we found out they could flip themselves through a moving window like a goddamn flying Wallenda. Now they can gang up on you and pick you up by your head?

I'll take a pursuing swam of flies over this any day:

Scarier than flying monkeys, if you ask me.

Re: earlier comment about "airplanes lose their trim tabs all the time"...

Early P-51's were delivered with cloth covered elevators (the moving surface, not the fixed horizontal stabilizer); later versions were retrofitted with metal covered elevators. Cloth covered were used to reduce the incidence of aerodynamic flutter, as they were more naturally damped. The loss of the tab could have indicated that there was a failure due to flutter.

It's also possible (any others know more about this?) that this was a booster tab, used to actually drive the elevator - the control linkage moves the tab down, the elevator moves up in reaction, the plane goes up in response to that. No booster, no elevator.

Where do you live?

Since last summer, FiFi has a new home at the Cavanaugh Flight Museum at Addison Airport in north Dallas. I live about 1/4 mile south, and about one mile east of the end of the runway, right under the departure path for winds from the south (about 80% of the time).

The NTSB released the proximate cause of the crash of the Galloping Ghost as high speed flutter due to loosening fasteners in the elevator trip tab assembly. There is an amazing amount of data (ie, science) in the docket:

http://dms.ntsb.gov/pubdms/search/hitlist.cfm?docketID=51746&CFID=256561&CFTOKEN=82086778

with a final report synopsis here:

http://www.ntsb.gov/news/events/2012/reno_nv/index.html

The most damming quote from the report summary is:

“In Reno, the fine line between observing risk and being impacted by the consequences when something goes wrong was crossed,” said NTSB Chairman Deborah A. P. Hersman. “The pilots understood the risks they assumed; the spectators assumed their safety had been assessed and addressed.”

One of my Favorite aircraft Is the F-82 Twin Mustang. Take one of the most epic aircraft in history and double it. There is one on static display at Lackland AFB in San Antonio (along with an sr-71).

Way back when, it was easy for anyone to just drive on base to see this display. Is that even possible today?

Seeing a football field doing snap rolls is my poo poo.

Barrel rolls, maybe. Snap, no. You still have to deal with inertia along the thrust axis, and that thing has football fields worth of inertia.

That's a cold solder joint if ever I've seen one. It was bad from birth, cracking or no. I blame lead-free solder.

What would that be used for? Research?

It would be really good for this:

tl;dr: orbit an ultra-high resolution camera over a crime-ridden area of the city, DVR'ing the action. Crime happens, play forward and backward from the event to know where the perps came from, where they went. Nab the bastards. Privacy violation? Maybe, or not.

You gotta be thirteen to be the remote pilot in charge, so I think you need to have an adult on a buddy box. Either that, or maybe you just have to have an adult nearby making sure you don't fly your Super Cub into a 747. Consult your lawyer / your local AMA field's rules.

Tell that to this kid: https://www.youtube.com/watch?v=JHJs1gBLiuQ

There are videos of him just "flying" at 4.
