Query: Skew Dyck paths with catastrophes   Skew Dyck paths are like Dyck paths, but an additional south-west step
$(-1,-1)$ is allowed, provided that the path does not intersect itself. Lattice
paths with catastrophes can drop from any level to the origin in just one step.
We combine these two ideas. The analysis is strictly based on generating
functions, and the kernel method is used.
