The Covid-19 pandemic started in 2019 and lingered on well into 2021. During this peak many exercises and airshows were cancelled. Flying operations were downgraded to a minimum. This explains the minimum of events.

The war between Ukraine and Russia which erupted in 2022 had a very different influence: (European) countries started to expand all of their military forces and practically all air forces at this moment ordered more and/ or new aircraft. Another huge change are the massive European and US deployments, daily CAP's over Eastern Europe and increased transport movements - even Australia (C17's) and New Zealand (C130's) have transport activity over Europe.

ADS-B is becoming a common used interface by spotters as wel as many other people - therefore I will add photo reports per year about interesting ADS-B spotted aircraft.
