Interesting real-world tractor motor rocket

I saw a video of one of these on Facebook and then found this via Google. The MK 22 is a mine clearing rocket that features canted tractor motors and is mostly finless.

In HPR, head-end ignition is a thing. This rocket features the more standard tail-end ignition...except the nozzles are on the head-end. So, this is like a flying head-end ignited HPR motor with a nozzle assembly that points in the wrong (opposite) direction? Push me pull you!

Cool airplane, but a tractor-motor nightmare

Last year, a crazy rocketeer built a flying model of an ekranoplan. Forward mounted tractor motors and a canted cluster...what could go wrong. That rocketeer doesn't know since he hasn't had a chance to fly it yet. But he saw this airplane in the latest issue of the IEEE Spectrum and started getting more insane ideas...

Reinhardt Engineering TU 523 VTO freightliner
This spring, Reinhardt will fly a 1:4 scale version on a 60 day, multi-country test flight. If the aforementioned ekranoplan flies successfully, maybe an even smaller version of the TU 523 might fly in the summer. Naw, probably not, but crazy rocketeers are allowed to dream.
