None in regular airline service. I have seen a couple of
707s converted to corporate service where the forward cargo

outside the cargo door for engine starts and then shut-down

I've een told, but haven't seen, that some have the 727 type
installation.

I understand the 727 was originaly designed without an APU and they
squeezed one into the wheel well. This was the main reason it couldnt
be used inflight. This was from a systems instructor who had alot of
folklore on the 727 (Including the picture of 30 or so people hanging
on the airstair inflight during the fall of Siagon).


Could be. I only flew th e200 and they all had them. Of course, you
didn't really need one in flight anyway. There were plenty of electrics
available from the three engines anyway.
