So, you are basically saying the a/c is stationery at a fixed point on the
ground - so there is no actual airflow (assuming it is in a closed area) so 
the
aircraft cannot attain T/O speed - hmm mind you there is no airspeed so it 
will
not go any where.


Well that my logic but there again I am a 79 year old (in June) pilot so what
do I remember from the ATP/IR course of many years ago :(

Mind you physics does somewhat play a part....
