ATC cannot see anybody at FL700 only if they squark mode C and I doubt very much a Russian AF does that, even then they could easily fix it so it looked like 700 🙁

magnificant TUAF F-4 pictures

Tuncay Deniz has just published this book about F-4 in the TUAF. Fantastic pictures

I live in Cahors and it seems that there is a system that flights from Cazaux are allowed low level navation flights, one flight a day along the Lot river. Mostly Alphajets, but at least once a week a two-seater Mirage 2000 and occationally the VERY noisy Rafaele. Helicopters are the Cougars in grey. 🙂 I love the noise of FREEDOM!!!!

it is an old chineese AF target drone!
