That’s up a little but I don’t think it’s anything like full up.
Check out this picture of a Mustang on the ground, that is what full up elevator looks like. Now ok, the Reno aircraft was heavily modified but it still needs to slow down for landing and the slower you go, the more up elevator you need, so it still needs a lot of control movement. I doubt that picture shows anything like full up elevator. This is a red hearing though, at the speeds it was doing it doesn’t need to have full up elevators for it to pull excessive g (by the way, where has the 10 g figure come from?)
The 10g figure came first from estimates by pilots who observed the climb, then by telemetry data from the Galloping Ghost, which I think reported 11 g’s in the pull-up. In addition, the Voodoo Chile trim failure exerted 10g’s and looked very similar.

The net table control is the successor to the v1.x DataGrid, adding the skills to usurp asset of specified capabilities of ASP.NET evidence roots controls. Whereas the v1.x datagrid net required a page developer to write usage principles to handle simple operations such as paging, sorting, editing or deleting observations, the GridView direct can automatically tackle these operations provided its obligated data table html roots be in control of supports these capabilities. The GridView also offers some functionality improvements on the other side of the DataGrid, such as the talent to define multiple primary tone fields, and some UI customization improvements, such as late-model area types and templating options. It also exposes a original model in place of stage developers to command or cancel events.
In the above sample, the GridView conduct reflected against the fields of the evidence records returned during SqlDataSource in order to dynamically give rise to the columns of the grid. You can data grid also specify plain column fields to dash by adding DataControlField objects to the GridView’s Columns collection. This allows you to itemize unerringly which columns to exhibit and their relative order. The following example demonstrates a gleaning of BoundField and CheckBoxField objects in the net grid collection. Other field types that can be assigned to this amassment are ImageField, HyperLinkField, CommandField, ButtonField, and TemplateField.
Moment to everything it can prove that you want javascript table to make your html edibles more attractive and more interactive. Charter out’s surmise you hunger for to make allowance your visitors to silverlight datagrid and display some best rows in your table. Of certainly you are here because you thirst to do it without reloading datagrid. It is doable with javascript to cover bring forward rows and make clear it again later if you want.
Foremost of all lets contrive a prime and elementary html 3x3 ajax grid where the primary tiff contains the column captions. With the following html traditions:
My colloidal solution uses JavaScript, as CSS3 isn’t truly a viable option yet. Browsers today unruffled competition to support CSS1 and CSS2. Unvaried notwithstanding that HTML tables aren’t recommended pro Cobweb period javascript grid, they are quiescent perfectly suited to the presentation of tabular data. In this tutorial, I’ll put on show three examples based on the uniform idea. I have tested edit gridview the solutions in IE6, Firefox 1.0, Mozilla 1.7.3 and Opera 7.54 on the Windows plank only.
I saw the wheel down and it didn’t register that it lacked a stowed locking mechanism.
Even a tiny amount of vaporized gas would ignite in a spectacular event. A gallon of gasoline would have exploded violently and there was certainly much more than that on board. There is no way to avoid an ignition source upon impact so something intervened in that process and this seems like the most likely scenario.
It’s hard to say if the trim tab failed or the control linkage failed failed first. Without looking at a schematic of the control system I’d have to guess that the most stress on the trim system would be on the trim tab lever (the part the cable attaches to in the tail). Cables are stranded wire taking the load in tension and the pulley’s take the load at a 1 to 1 ratio (at most) against their shafts and attaching points. The levered end of the trim tab is taking the load and magnifying it through the force of leverage. It’s like bending a stick over one’s knee. It’s going to snap at the pivot point.
Regardless of what broke first a trim tab that is loose could easily flutter apart in seconds. I don’t know if anyone has ever experienced a resonating part it’s amazing how violent it becomes in so short amount of time. I had a wheel bearing go bad in a car and the wheel assembly would resonate at a specific frequency causing then entire car to shake violently. Not only would my exhaust system start the event but a passing truck could trigger it. the time between the first hum of resonance and violent shaking was just about enough time to slam on the brakes.
This gentleman was in the box to theright of the box that the wheelchair-bound man was located.
Does anyone know if locking the right elevator trim tab in place, as it appears Leeward’s crew did, is a common practice when modifying an aircraft for racing? If so, I think it is in the same category of normalization of deviance that plagued NASA in the Shuttle program.
You may want to turn the HD off before downloading this video, otherwise it may take a along time. It replays the final turn in slow motion.
The video shows the whole race. Rounding the final pylons, The Galloping Ghost increases its left bank to more than 90 degrees. There is a possibility that he may have hit some turbulence from Voodoo. When Leeward gets it back to what appears to be a 90 degree vertical bank, there is a huge positive pitch imput, enough that this is when the tail wheel is forced down and, maybe is when Leeward blacked out. I think a highspeed stall occured at the same time, since the aircraft then rolls to the right at a rate that the cut down ailerons were probably not capable of producing. The trim tab, in my opinion, did not cause any of this.
Have you been to the races? Turn 8 is quite a long way from the crowd. These airplanes are typically only about 50-200 ft from the ground.
Again, this accident was quite a fluke. For that airplane to get to the box seats, it had to fail in a way that caused it to gain altitude, barrel roll towards the crowd, and take out the pilot so he couldn’t correct the flight path.
The last time a trim tab failed on a P-51 at Reno, the pitch-up caused the wings to rip off, and the whole thing went into the ground a long way from any people. There have been many crashes at Reno, including crashes and mechanical failures that happened around turn 8 and turn 9, and until now none of them have come anywhere near the crowd.
We don’t need to react to every fluke accident with major changes and new rules. If some minor changes to the course layout can improve the vectors of the airplanes to make the crowd a little safer, fine. But if the race is radically changed, and those changes put the airplanes a long way from the crowd, it will simply kill the races. No one’s going to sit in the bleachers to watch specs in the distance through binoculars.
Again, this accident could have happened at any airshow, even under U.S. rules. If anything, the aircraft come closer to the crowd at airshows than they do at Reno.
And going at 500 mph. If the planes dropped like a rock from that height and speed they can still cover 2-3000 feet. Since they aren’t rocks, but machines that can fly, that distance can get big quickly. There’s no realistic safe distance away from an out of control airplane coming at you.
The point isn’t distance, it’s direction. You may call it a fluke, but it isn’t. The pilot lost control around a difficult turn and crashed in the general direction of the flight path. That’s not flukish. That’s what you expect to happen. No one is talking about onerous safety rules. We are talking about basic common sense.
‘The last time a trim tab failed on a P-51 at Reno, the pitch-up caused the wings to rip off’
This was Miss Ashley II in 1999. Initial thoughts blamed it on the trim tab, but the final analysis showed that the wing, which was from a Learjet and had been repaired from a previous incident, failed first, sending parts into the tail causing it to fail.
The point is, the land simply isn’t available. The grandstands are permenant, and where they are. Thats where the crowd has been, and always will be. Thousands of people are not going to go hike into the desert to squat on private property to watch the races.
Again, have you been to the races? Turn 8 is a long way from the crowd.
That’s not true. The Galloping Ghost did not crash along its flight path. As I’ve said repeatedly, it climbed up out of its flight path on a high, wide barrel roll towards the crowd. Had it crashed along its flight path it would have impacted the ground roughly 1/4 mile from the audience.
When a plane is flying laps, every point on earth is along a tangent to its flight path. It is a fluke that a crashing plane hits one point rather than another, and the farther away from its planned path the more of a fluke it is.
Yes, I have. And I wondered what would happen if someone lost it on the turn that lines them up in front of the crowd. Pretty much what I suspected would happen only I envisioned the plane hitting the stands.
(2) If the land is that densely populated around the airport, why in the world are they holding air races over people’s homes? And come on, they can’t find a field around Reno freaking Nevada? It’s not Manhattan.
(3) Permanent Grandstands? Heavans, we might as well try and move Mt. Everest. I’m sure the upcoming lawsuits will be several hundred times the cost of grandstands.
