REACH 927: C-17A with tail 89-1192 working with ATCC Dutch Mil on 240.9000 MHz > 120.8300 MHz. They had difficulties with radio reception, so that's why they were on UHF first.
BASIC 51: callsign heard to understand, so not 100% sure. Mode-S shows 2 F-16's: FA-114 & FB-15; working with ATCC Belga Radar on 278.4750 MHz > 240.8500 MHz.
