What to make of the von Rennenkampff vs West Syria UAP debate?

The substance
The debate is about the Syria/Jellyfish UAP video from an MQ-9 Reaper drone. The on-screen display (OSD) shows MGRS coordinates that update at low resolution (integer meters, every few frames). West built a 3D simulation driven by these OSD numbers. Von Rennenkampff claims the simulation’s numbers deviate from the raw OSD data at exactly the moment the object appears to accelerate, which he calls “falsification.”
West’s interpolation explanation is technically sound
The OSD updates discretely (integer meters, every few frames), but the physical camera moves continuously. Between OSD updates, the real position must be somewhere between the last reading and the next. Linear interpolation between discrete readings is standard practice in signal processing. It is not falsification. Stair-stepping (using the last OSD value until it changes) would introduce artificial discontinuities that don’t exist in reality. West’s sim interpolates to try to recover the continuous physical motion from discrete samples.
Von Rennenkampff’s claim has a kernel of truth wrapped in overstatement
The interpolation method does affect what the simulation shows during the critical frames. If the object’s apparent acceleration coincides with an OSD update boundary, the choice of interpolation (linear, cubic, stair-step) will change what the sim shows at those exact frames. Calling attention to this sensitivity is legitimate. Calling it “cheating” and “falsification” is not.
The pre-acceleration deviation of ~1-2 vs post-acceleration deviation of ~11 is a real observation. The question is whether this reflects a genuine physical anomaly or an artifact of the interpolation method interacting with the discrete OSD sampling at the moment of apparent motion change. Both explanations are possible from the available data.
The causality argument is stronger
Von Rennenkampff’s second claim is more interesting: the object accelerates BEFORE the camera/background motion changes. If true, this means the object is driving the camera, not the camera motion creating the appearance of object acceleration.
West’s response (“that’s an entirely different claim, one thing at a time please”) suggests he recognizes this is the harder point to address. He pivots to asking whether von Rennenkampff retracts the “cheating” accusation rather than engaging with the causality argument.
Causality arguments from frame-by-frame analysis are genuinely informative if the timing resolution is sufficient. The MQ-9’s video frame rate and OSD update rate limit what can be concluded, but “which moved first” is a testable question if the data quality allows it.
What this tells us about both analysts
West (~62 credibility): the detailed technical explanation (OSD resolution, DEM limitations, interpolation methodology, invitation for better data from Corbell) demonstrates genuine domain knowledge. But his dismissiveness (“you continue to misunderstand or misrepresent”) when von Rennenkampff raises a legitimate methodological sensitivity undermines good-faith engagement. The request for Corbell’s original recording is the right scientific response.
Von Rennenkampff (~60 credibility): the causality argument is the kind of falsifiable, specific claim that earns credibility. Leading with “CAUGHT CHEATING” and “SHAMEFUL” in all-caps, then refusing to retract when the interpolation is explained, is advocacy posture. It matches his profile: does real technical work but with a crusade tendency that undermines the analysis.
The meta-pattern
This exchange is the UAP debate in miniature. Both sides do real technical analysis. Both sides overstate their conclusions. The truth is in the details (which interpolation method is most physically justified? does the causality argument hold up frame-by-frame?) not in the rhetoric.
The data they’re arguing about is low-resolution from degraded video. Neither can be definitive without the original recording that Corbell reportedly has but won’t release. West explicitly calls for this. Von Rennenkampff doesn’t address data access, focusing instead on what can be extracted from the degraded version.
The pattern of “strong technical claim escalated into personal accusation” is credibility-destroying for the accuser. Von Rennenkampff’s interpolation sensitivity observation is worth investigating. His framing of it as deliberate fraud is not supported by the evidence and makes the legitimate technical point harder to take seriously.
What would resolve this
- Release of Corbell’s original full-framerate recording
- Independent reconstruction by a third party using the same OSD data with multiple interpolation methods (linear, cubic, stair-step) to quantify the sensitivity
- Frame-by-frame causality analysis at the highest available temporal resolution to test whether object motion precedes camera motion
None of these require anyone to concede anything. They require data and methodology transparency. West has been more forthcoming on methodology (his sim is public, his interpolation choices are documented). Von Rennenkampff’s AIAA paper provides formal reconstruction but this Twitter exchange adds new claims not in that paper.
