Published Covid Study: Does it show virus transmission on flight?

Interesting study, does not identify flight or source airport but highlights that all passengers were from stopover from other flights.

The study (attached) shows the infected passengers by seat layout.

It appears to say that transmission was in-flight.

An outbreak of 59 cases of coronavirus disease
(COVID-19) originated with 13 cases linked by a 7 h,
17% occupancy flight into Ireland, summer 2020.

The flight-associated attack rate was 9.8–17.8%.
Spread to 46 non-flight cases occurred country-wide.

Asymptomatic/pre-symptomatic transmission in-flight
from a point source is implicated by 99% homology
across the virus genome in five cases travelling from
three different continents.

Restriction of movement on arrival and robust contact tracing can limit propagation
post-flight.
