Correct answer: B — Defer flight or use a drained chest with a one-way valve when urgent

The best answer is “Defer flight or use a drained chest with a one-way valve when urgent”. A pneumothorax is a contraindication to air travel because trapped intrathoracic gas expands as ambient pressure falls and may convert to tension physiology. The CAA advises travel after successful drainage and full expansion, or earlier only with a chest drain attached to a one-way Heimlich valve when clinically necessary. Stability on the ground and supplemental oxygen do not eliminate this pressure-related risk.
