The US security team yesterday surveyed the road President Barack Obama will use after landing at the Jomo Kenyatta International Airport (JKIA) in Nairobi today.
The MV-22 Ospreys helicopters protecting Obama flew over the city piloted by US Marine Recon teams.
The powerful Rolls Royce-Allisson turbo shaft engines shook the Standard Group Centre as they flew past to JKIA.
The aircraft are part of the HMX-1 Presidential Squadron based in Quantico, Virginia, USA.
The helicopters have been the primary assault support aircraft of the US Marine Corps since 2007.
Each has a crew of four – pilot, co-pilot and two flight engineers – and can carry up to 24 troops and extra ammunition.
