While browsing new videos at flightlevel350.com, I came across this one. The gear is not retracted, even well after takeoff. Maybe they were waiting to clear a specific altitude? they forgot? special procedure for a freighter? i know 747 tend to leave gear down a tad longer than other aircraft, but this is quite unusual. Comments appriciated!

I think someone posted a similiar question some time ago about a different aircraft.
In that particular instance it was explained that in some cases pilots retract the gear late so as to let any tire dust be 'brushed' off by the air. I think someone also mentioned that leaving the gear extracted while climbing (for a short period) helps cool the wheels.
Some-one with some technical knowledge may provide a better explanation.

Quoting MD88Captain (Reply 2): Often a delay in gear retraction is used to cool the brakes and tires after a prolonged taxi on heavy weight aircraft.
Cooling is a highly likely reason.
A few months ago, during our summer season where the day-time temperatures hover just under 50C, I had a Syrian B74S depart, and they had still not retracted the gear when they were through 8000' and I had lost sight of them... I informed our radar sector, and they queried the pilot if there was a problem, and he said no, they had delayed retraction for cooling purposes...

Just out of curiosity:
I'm not a pilot, but have a question to the pilots here. That landing gear would have to cause immense drag. Is it possible that the pilot forgets to raise the landing gear that so much drag is lost that the aircraft stalls and crashed because it cannot gain/maintain airspeed?

On climbout from AMS enroute to SEA (NW A333) last summer, the captain of my flight actually put the gear back down to cool it off. It was a full flight, and we'd had a long taxi to 36L (not that there's a short one).
