A few points.
1. Gear up selection will increase drag for a little while, but very soon after drag will be back where it was before and then a big reduction in drag as its all stowed away, times like this you want all the 1 and 4 EDPs and demand pumps plus all eng bleeds in working order, strange fact is the operation of the L/E will be using bleed air that the demands would like very much at that time
.
2. Gear up selection will also give a little pitch down effect, may of been a good thing on said flight.
.
3. Leaving gear down in case ground contact is made may be good in some events like a G/A, leaving gear down in this event may or may not have been good, had gear of made contact again, story could have a different ending.
.
End result was very very good, well done to all.
