TIP in the millestone missions you have included all the sporting events of the formula 1 F1 which has nothing to do with aviation except for some helicopters that do aerial filming. the real events that you have to look for are the various exhibitions of the various acrobatic patrols that are found throughout the world starting from the N.1 in the world Frecce Tricolori and then Red Arrows, Thunderbirds, Blue Angels etc. etc. then there are events such as air races such as the REENO air race and I also recommend that you see the various events on the RED BULL AIR RACE website which also include formula 1 F1 and MOTOGP events as well as air races… this is the link.https://www.redbull.com/it-it/tags/air-racing
you can also go and see directly on the FAI website here is the link…https://www.fai.org/..in addition there are also events that concern exhibitions and fairs that concern the world of aviation such as one of the most important which is the fair in Friedrichshafen that this year was in April and you missed it and in addition there are also local and regional events of various nations where there are small air missions that are not taken into consideration.

some events like the one you posted, the IESOLO air show event, are not sponsored by organizations like the FAI but by military organizations like the air force. Each nation has its own air force and I think that each of them has events.
