Aircraft Equipment Problem Critical
Flight Crew Returned To Departure Airport
Aircraft
On takeoff roll; the First Officer's pitot gauges all flagged. We continued the takeoff. Once at a safe altitude; we ran necessary checklists; notified Maintenance and Dispatch; got a new clearance and release for ZZZ and returned. We planned for an overweight landing. Approach kept us fast and after dropping the gear and running the checklist which includes a recall check; we noticed the speed trim fail and mach trim lights illuminate on recall only. This distracted the Captain for enough time to look up; evaluate; but get a little high on the profile. We opted for a go around. We ran all the checklists again and returned for an uneventful overweight landing in ZZZ.
A B737-400 First Officer reported losing his pitot system on takeoff; resulting in flags in all of his pitot-driven gauges. They elected to return to departure airport.
