Victor hatches
Interestingly (but not for the crew!) a similar hatch incident occurred in the early eighties. As the Co adjusted his seat down in mid sortie, the seat emergency oxygen bottle fouled on a poorly routed hatch jettison cable, causing the hatch jettison to operate with the same results as in the post above. Needless to say, the pins went in pretty sharpish, followed eventually by an uneventful landing.
