Did anyone else happen to see a plane flying backwards over Lincolnshire on Sunday evening?
Or can shed any light as to what it might have been?
It had a wide wingspan like a glider but was powered by a propellor which was at the front except the whole thing was moving backwards which would of course mean the propellor was at the back as I saw it..........
its against the laws of physics to fly backwards, there are some planes out there with engines at the rear and small wings at the front which would give the impression of flying backwards

As you can see, this is nothing new. As speed increasing it becomes virtually impossible to keep the machine on a steady level with the elevators in front. A bit like those early rubbish trucks having the steering at the back wheels - very effective but difficult to control at speed.
Suppose a small aeroplane can cruise at an airspeed of 70mph and it is flying into a headwind of 100mph. To an observer on the ground the aeroplane will appear to be flying at 30mph backwards.
