One thing for sure, the FAA will blame the pilot.

It seems that he may have had the plane up for sale. There is a web site that has all of the specifics .... http://www.jackairllc.com .. and though the full content has been removed, the "cached" information in the form of the text is still fully stored.
It lists things like spoilers, max speed of 300 mph, TSIO-520-NB (300hp ??), Flint tip tanks and a fuel capacity of 163 gallons. How would the combination of horsepower (he lists the top speed as 300), and things like the spoilers affect the aircraft. Here, I get fully lost; wouldn't it be SOP to have the spoilers out for a descent? The interplay between the engine mods and the tip tank/STOL mods? You folks will understand what he had and it sounds like there was little held back in building this ship with the electronics like a stormscope etc. The posted link did not work ... but ... just Google in .... riley super skyrocket .... and it will be a few from the top and you can see the jackairllc tag .. hitting the cached feature will bring up the text.

You wouldn't use spoilers or speed brakes from a starting altitude of 1400' in a "watch this" dive. You would use them in a controlled descent from altitude to avoid overspeed. I am not familiar with the Rocket, but isn't the 300+/-mph an issue of 2% speed gain per 1000' and it flys at 30,000 feet, thereby increasing the groundspeed but not the IAS? I can't imagine that the Rocket has significantly different operating parameters than a regular of pressurized 337.

The advertising of the Super SkyRocket said max speed 300 MPH, cruise speed 250 MPH, that was all at 20,000 feet. On an ISA day, flat out, you could achieve a true air speed of 300, they said. No one would fly flat out, for more than 5 minutes, at any altitude. The cruise, again, was at 75% power, and again at 20,000, oh and at medium weight.
That all translates to advertising stuff, and the theory that as altitude is gained, resistance is lessened.
