Hawkers - tough as old boots
Blimey, that doesn't look so good. Hawkers of course are legendary for their strength and ability to fly when all 'essential' systems are lost. There was the famous Botswana/Malawi Hawker 800 that had an engine shot off by a sidewinder over Angola I think - holes everywhere but pilot landed safely and considered flying out again with litterally one engine, hydraulic pipes dangling everywhere. Was repaired and still flies today. Highest time Quantas training Hawker did 50K landings or more I think. The USAF did some rolls in theirs when testing the C-FIN aircraft used for flight inspection.
Manual flying controls - all cables and pulleys and can fly with no electrical power or hydraulic services whatsoever. Maxaret brakes make for excellent landing performance with full blown lift-dump, aerodynamic brick wall.
Hawkers - indestructable. No safer business jet when all is lost and nothing works!
