Tuning 'in and following'

The Royal Air Force – the world's first independent air force – was founded on 1 April 1918, independent of the British Army and Royal Navy. 
For one hundred years the RAF has defended the skies of Britain, preventing conflicts, delivering aid and combating cyber threats while working in partnership with other Services, from Operation Ruman – the UK's humanitarian assistance operation in the aftermath of hurricane Irma which hit the Caribbean in September 2017, to the RAF's Quick Reaction Alert Typhoon Aircraft, providing a UK air defence capability 24 hours a day, 365 days a year. .
Today the RAF is engaged on some 13 missions across 26 countries and is heavily committed on operations both at home and abroad.
