Sheilanagig,
Not entirely true (reg HF) I flew a Lear 24, 4-5 yrs back, NY-Bermuda no HF...Had to have a letter from NY TRACON and not be out of VHF coverage for more than xx minutes, sorry can not remember for how long but a Lear was within...
Not everything's as the books state
, some research might prove fruitful.
