So to get the less obvious out of the way first, the camouflaged propeller plane being fueled in the background is a Yakolev Yak-52, a Russian military primary trainer. It's a civilian version, but the Yak-52 is a rugged, easy to maintain aircraft.
But now for the more obvious. The larger white jet is a Learjet 45. It seats 9 passengers, has a range of 1,710 nmi (3,167 km), and has a ceiling of 51,000 ft (15,545 m).
The smaller jet with the elaborate paint job is a Cessna Citation M2. It can carry 7 passengers, has a range of 1,550 nmi (2,871 km), and has a ceiling of 41,000 ft (12,497 m).
So perhaps the plain white LJ45 speaks for itself, and the M2 with its flamboyant livery is, um, compensating. I leave that to the reader to decide.
Whenever I fly I take my Learjet, one finds it so much classier than a smaller Cessna and one's champagne cocktail tends not to vibrate so much. (I wish!)
