VFW614 - overwing mounting
The VFW 614 was an unfortunate commercial failure, being unlucky with initial engine choice. Yet another in the long long line of DC-3 "replacements", it's most notable feature was the over wing mounting of the engines.
The only other example of overwing mounting of anything I can recall was the fuel tanks on some Lightnings.
Can any of our esteemed readership give me any other exampes of overwing mounting?
I can see the obvious disadvantages of putting missiles there, a misfire or jettison is going to put the flaps and tailplane at risk, but other than possibly cabin noise, I'm intrigued as to why other designers have not opted for a low-wing and mounting the engines on top.

One reason for the mounting could be that it keeps the engines away from debris. Very useful if you're planning on operations from secondary/rough strips.

Heathrow Director - Aye you are correct there, how did I forget the Antonov?

Hadn't paid too much attention to the HondaJet either. Unlikely to be able to afford one this month so it slipped my mind. I have a lottery win scheduled for April though so we'll see about it in mid May once I have the mansions sorted out.

How is it possible that no one has mentioned the Jaguar yet? Missiles on top of the wings. Great idea. I can vouch for the fact that it is quite noisy when you fire one though.

Bob Viking - unaware of that one too - can you link me to any photos?
In view of the performance characteristics of the Jaguar, can you tell me if there was any truth in the rumour that wire-guided missiles were considered with main use of the wire being for towing said Jaguar?

Yes, indeed, the English Electric (BAC) Lightning had over-the-wing ferry tanks and rocket pods, (rocket pods shown below):
A few more over-the-wing designs:
NASA's proposed AMELIA design, (below), has engine pods similar to the VFW 614:
The Rutan Triumph (below)

While this may not qualify as an over-the-wing design, the D-21 Mach 3+ drone mounted on the Lockheed M-21 was tres avant-garde !
The AVTEKAIR 9000T certainly qualifies as an over the wing design:

From a design standpoint, wouldn't over-the-wing mounted engines at high power (e.g. take-off) cause a nose-down pitching moment that would necessitate an even larger than usual downforce required from the tail? Hence beefier tail, beefier rear fuselage, hence higher structural weight and reduced payload?
ISTR the VFW614 had aeroelasticity problems too, but I cannot remember the details.
Any designers care to comment?

VFW614
I flew in one as a pax.
From Copenhagen (Kastup) to Sonderburg (SP). Circa 1974-5.
I'd never heard of the a/c and when I saw it, my 1st reaction was 'WTF?'
But it seemed to work

There is also the Custer Channelwing, although it is more like Wing Under Engine than Engine Over Wing:
