    1. [Project update] The drone now flies the same building with no map, no GNSS, no magnetometer and no lidar: two cameras do both the seeing and the localizing (ROS 2 Jazzy, PX4 SITL, Gazebo Harmonic, CUDA MPPI)
    2. ROS2 Visualization tool for iPad
    3. [Project update] The drone navigation stack now flies a real 3D urban location with no map (ROS 2 Jazzy, PX4 SITL, Gazebo Harmonic, CUDA MPPI): what changed since August, and what five crashes taught me
