The paper you've provided, "Reconstruction of Potential Flight Paths for the January 2015 'Gimbal' UAP" by Yannick Peings and Marik von Rennenkampff, offers a detailed analysis of the infamous "Gimbal" video, a piece of footage depicting an unidentified anomalous phenomenon (UAP) encountered by U.S. Navy aviators. The authors attempt to reconstruct potential flight paths of the UAP based on the data available from the video and eyewitness accounts.

The methodology employed in the paper includes:

Reconstructing the F/A-18F Flight Path: The authors use the indicated air speed and the rate of turn data from the ATFLIR (Advanced Targeting Forward Looking Infrared) display of the F/A-18F to estimate the flight path of the jet. This reconstruction is critical to understanding the relative movement between the jet and the UAP.
Estimating Lines of Sight (LOS): By analyzing the azimuth and elevation angles from the ATFLIR display, they determine the potential directions in which the UAP could be located relative to the jet.
Potential UAP Flight Paths: With the LOS and the jet’s flight path known, the authors explore potential flight paths of the UAP. This involves considering the impact of wind and other factors to match the observed behavior in the video, such as the UAP’s apparent stop and reverse in direction.
Analysis of Various Hypotheses: The paper also addresses alternative explanations for the UAP's appearance in the video, including optical artifacts due to the ATFLIR's mechanics and the possibility that the UAP was a distant conventional aircraft.

The authors' analysis leads to the conclusion that, within the constraints of their assumptions and available data, the UAP displayed highly anomalous flight characteristics. These include the ability to stop and reverse direction in a vertical maneuver, exhibiting low speed at high altitude without visible means of propulsion, and lacking conventional aircraft signatures like an exhaust plume.

The mathematical and physical principles applied in the paper, such as the use of standard aviation formulas for calculating rate of turn, true air speed from indicated air speed, and wind effects on flight paths, appear to be correctly applied. The assumptions made about the wind conditions and the interpretation of the ATFLIR data are based on the available evidence and seem reasonable within the context of the analysis.

However, it is important to note that the analysis is heavily dependent on the accuracy of the input data (like the wind speed and direction, F/A-18F's flight path, and the azimuth/elevation angles), and the authors' interpretations of the video footage. Small inaccuracies or misinterpretations in these inputs can significantly affect the conclusions.

In summary, from a technical standpoint, the mathematical and physical analysis in the paper appears to be sound, given the constraints and assumptions inherent in such a reconstruction. The paper represents a thorough and methodical attempt to understand a complex and ambiguous aerial encounter using available data and standard principles of aviation physics and mathematics.
