Ah ha - the D B Cooper method of leaving the aircraft albeit on terra firma !
Yes I know that was a 727 and not a Mad Dog !
But you did not have to wait another 20 minutes for the truck stairs to arrive
to find an alternate way without popping emergency door hatches and slides
to a concrete landing pad.
So tell me who tripped the circuit breaker in ATL gate control disabling the
jetway ? Very unusual.
