18hrs in a plastic pig - no thanks!
The U2/TR1 mission is about 10-12hrs, they use a catheter type device and have astronaut style food - and they are next to useless for the next day after a mission. If we are really considering this for 18hrs then the UAV option has got to be the only way. Even at 12hrs the crew will be knackered and their performance will drop right off after 8hrs or so.
If we're considering less than 8hrs then why not go for something bigger like a KA-350 or Islander, if you know what I mean
Or buy more Reapers with weapons' clearances and 8hrs+++ on station? Or a Zephyr derivative with 3 day's+ endurance?
I can't understand what this GA tourer will bring to an already crowded party???!
PS This is a Zephyr and its a British bit of kit...
