FR 24 came to rescue on trying to figure out noise above the clouds in fgrome today, fair amount of military activity but mostly hawks and this had a far deeper stronger sound. FR24 had it as 2 USAF F15s Shark 31/32 playing at tailchasing over Frome at about 14000 feet , a couple of wide orbits but both tracks crossed right over the town -although a few miles apart . Not seem/heard that sort of USAf presence here before and wondered what they were up to.
later in the day RAF Herc belting along very very low, FR 24 showed altitude/height as 250 climbing to 350ft . certainly looked extremely low as it sailed by heading for Brize no doubt, a great sight. I assume there is some sort of limit on height above terrain for military flights , . Low level Hercs are not uncommon but this was exceptional . Very hard to judge height above ground as frome is something of a funny shaped town being ina valley surrounded by low hills-upto 400 fr amsl, where my house is which rapidly drop down to flat lands about 100ft amsl which is where I saw it from and only .a mile or so away. A fun view from the flight deck I am sure
