Nah health and safety put a stop to that. lense stores need to be fresh, updated every week or so. That means a RAS or helo drop. Trouble is bomb scares. All the little foil packets have to be scanned and sometimes opened before getting on the flight. Takes forever.
If i were you Gav, i'd have a quiet word with specsavers and see if they can slip you an extra box or two. Sneek it onboard and hope you can hide it come inspections.
And then hide a pair of glasses just in case. Be prepared, or something....
yes ,having your rectum reamed is still a hazard in the navee. Unfortunately regulations prevent the issue of vaseline so bring your own or make friends withe cooks who will let you have some beef dripping for a small fee
