Sometimes I wish we could send these daft Einstein wanabees forward twenty years to evaluate their grand schemes in hindsight.
They could then read the news headlines that spoke of 1000 plus people dying in one accident involving the midair collision of two large civil airliners (A380's perhaps).
The catchline underneath would go something like:- "Airlines put their profits ahead of safety by flying dangerously close to save fuel."
Hijackers could bring down two (or more) airplanes by hijacking just the one.
Why not save weight by doing away with engines on the trailing aircraft and just towing them across the pond as giant gliders?
NOTOPS?
If something seems too good to be true....it probably is!
