SFCC - Because people can show off how cool they are by listing a route as if they're filling in a flight plan, it makes them look big and clever.....
Be aware that Boscombe Down is generally still active at the weekends, and although you'll probably be given a blanket MATZ penetration (although remaining clear of the ATZ), you will still find a relatively high traffic density around that area - Tutors from the UAS/AEF at Boscombe and GA from Old Sarum, Thruxton, and Boscombe, as well as all the other people en-route to Compton Abbas!
If it's your first time visiting Compton Abbas I'd definately recommend approaching from the North, as it's notoriously difficult to identify from the South, despite the strobe!
