Hi Mark Nine,
The Lynx can take it (partly).
There where two near similar incidents, one with two german Navy Lynx and relative short later with two british Lynx, they just didn't belive and had to try themselves ;-)
While doing formation flying - they flew just a little bit to close and touched rotorblades....
On both occasions all helicopters managed to land - the germans on their frigates, the british did it over land - so no deck landing required.
From the german side:
One helicoter lost parts on all four main rotor blades....
the other one had bend edges.
The one with the bend edges had the worst vibrations.
Couple of years later one Lynx lost a part out of one blade - about an meter or so from the point where the folding gear is normally attached.
They decided to ditch and were rescued later.
But prolonged flight isn't recommended ;-)
Greeting Flying Bull
