Intruder,
Dropped off the tanker in the mighty Hun one night with lots of fuel. Lead asks for a block to 430. Controller approves and watches us fall out if the sky in the low forties, one by one each plane reached its exact coffin corner. Fun times, especially the descent waiting waiting for enough margin to pull a bit.
Years later, during Desert Storm, hand flew the C-5 across the Atlantic and once back up the Med from the sandbox.
OP,
If you are fearful of operating a jet within the prescribed envelope, may I suggest a career change.
