In the old days, an explosive decompression incident on a commercial airliner put you at about 30 000 ft; today it may well put you at 50 000 ft -- I would not want to take a serious DCI hit hours away from help (though O2 is readily available :-) just because of "technical difficulties"! -frank -- fhd@pa*.co* | To thine own self be true. 1 917 992 2248 | -- The Bard 1 718 746 7061 |
