JWKB Connection-Formula Problem Revisited via Borel Summation

The traditional version of the JWKB connection formula at a linear turning point is incorrect. The correct version follows from the Borel-based summability of the Airy-function asymptotic expansions. A key point is that the classically forbidden region lies on a Stokes line. The real exponentially growing solution has an explicitly complex JWKB expansion, while the explicitly real exponentially growing JWKB expansion represents a complex solution. Inconsistencies in applications of the traditional formula, such as in transmission through a barrier, are eliminated.
