Plus - a plane that's doing aerobatics when something goes wrong might go in flat, it might go in wing-first, it might go in tail-first, it might go in inverted, or it might go in nose-first. No way to put in enough air bags for that. It's the same deal with auto racing.

When you're going hundreds of miles per hour within feet of solid objects such as walls or the ground, there's simply no way to provide crash protection that's anywhere near close to what we expect from today's passenger cars at legal highway speeds. It's impossible, because such a system would have to defy the laws of physics. You can't slow a driver or pilot down that quickly in any practical race car chassis or aerobatic plane airframe, because the deceleration G-forces would kill them.

Ummm.... I was joking, sorry you missed that lol I was trying to lighten the mood here
Ok, let's get back to designing a ballistic ejector seat for ultralight aircraft...

Thereís just something about the thought of a pilot ejecting from his aircraft in the middle of an airshow performance thatís a bit unsettling. I realize there are times when it would make no difference whether he remained with the craft or not, but still I always think of the horrible Sknyliv airshow disaster in Ukraine when a SU-27 plunged into the crowd killing 77 spectators and injuring more than 500 after the crew safely ejected.

Anything less would be 100% unacceptable, as it's absolutely impossible to predict the altitude & attitude at which such a system would be needed during an unlimited aerobatic performance. Hell, the Air Force & NASA don't even have an ejection system that works from inverted flight @ typical airshow altitudes!

And assuming one could be designed, the result would be much too heavy for small aerobatic planes that typically weigh ~1000 pounds or less without pilot & fuel. It would also be way too expensive for the vast majority of airshow performers who aren't world-famous & don't make the big bucks.

yeah trust me i thought of that.... it'd require some ballistic control systems... and it probably isn't practical for 99% of the guys who fly... 100% agree.

That's really easy to say when you're not in that situation.

Iím pretty sure OhBee wasnít Monday morning quarterbacking - just alluding to Dracoís STOL capabilities, which (were ) quite considerable.

In his narrative, he said he had considered doing just that, but didn't want to run afoul of the field rules.

Well...the HH guys did say that they have other projects in the works with Mike.

With luck, hopefully we'll see an RC model of Scrappy - Mike's upcoming, absolutely insane, heavily hopped-up Carbon Cub that he's building out of a scrapyard Carbon Cub airframe & scrapyard parts, and powering with a boneyard Lycoming flat-8 with 780 CID & 500 HP!!!
