← ScienceWhich risk increases when an aircraft's relativistic kinetic energy approaches its engines' chemical energy output?
A)Increased parasitic drag coefficient
B)Engine flameout due to time dilation
C)Structural failure via mass increase✓
D)Uncontrolled acceleration toward black holes
💡 Explanation
Increased risk of structural failure results from mass increase because a significant fraction of the aircraft's total 'mass' becomes kinetic energy, per mass-energy equivalence. Therefore, structural integrity decreases rather than an issue such as engine flameout or increased drag.
