8. A-10 Thunder Bolt Weight Mass(m) = 13800 kg

9. A-10 Thunder Bolt Weight W = ?Mass(m) = 13800 kg

10. W = m ∙ g A-10 Thunder Bolt Weight Mass(m) = 13800 kg

11. W = m ∙ g = (13,800 kg) ∙ (9.81 m/s 2 ) A-10 Thunder Bolt Weight

12. W = m ∙ g = 135,378 kg ∙ m/s 2 A-10 Thunder Bolt Weight

13. W = 135,378 N A-10 Thunder Bolt Weight

14. W = 135,378 N A-10 Thunder Bolt Level Flight L = ?

15. W = 135,378 N A-10 Thunder Bolt Level Flight L = W

16. W = 135,378 N A-10 Thunder Bolt Level Flight L = W = 135,378 N

17. W = 135,378 N A-10 Thunder Bolt Level Flight (L = W) L = 135,378 N

18. SR-71 Blackbird Steady Flight T = 290, 000 N D = ?

19. SR-71 Blackbird Steady Flight T = 290, 000 N D = T

20. SR-71 Blackbird Steady Flight (T = D) T = 290, 000 N D = 290,000 N
