"....the boom is the only way to go"
Would seem to imply that there is no other way. Which is nonsense.
Hardly surprising if indeed the American mercenaries in their old 707 have offloaded a lot of fuel compared to the UK-based RAF AAR fleet - as it spends so much time in either the Malvinas or various $hitholes in the sandpit, thanks to the simpering little poodle's love for Dubya and all his wars.
