You have hit the nail on the head. MD say they delivered #100 and everyone believes they now have 100 of the things flying. Rubbish!
You first need to subtract 11 for serials #1, 3, 4, 5, 6, 7 and 9 which were ground test airframes, and #48 to 51 which were not built.
Next you need to look at the ones which haven't been delivered yet, like four for the Dutch police pre #100 ie #86/87/94/95 plus a number of aircraft still registered to MD which are sitting on the N register and not delivered #96/97/98/99
So at the point of delivering #100, they had shipped only 81 aircraft! (I am including demo aircraft in "shipped", but not everyone would)
Grant that there have been further deliveries since - they shipped #113 to Japan this week, but the other Dutch four (104/105/111/112) are still at Mesa so the figures are now 90 out of 113.
"maybe they have enough staff for the production they are doing" - chicken or egg?
Those Dutch ones... I wouldn't like to calculate the interest on the money tied up for that long - work out when #86 came off the production line in terms of what they have delivered the last few years... Also, in some quarters they believe that MD will never get the Explorer to meet the contracted spec and they will never be delivered to the customer. [incidentally, Rotor & Wing reported wrongly that the Dutch now have one new aircraft]
