Narrative:
During a short field takeoff at ZZZ at around 100 KTS; the tower controller mumbled something about abort and missing chocks. Nobody of the 4 crew members in the cockpit heard him clearly. Nobody understood nor acknowledged this transmission! We continued the takeoff roll and climbed out normally. The tower controller quickly; said 'air carrier X; contact departure' after takeoff. Which we did. All our cockpit indications were normal; takeoff was normal and aircraft handling was normal. The controller never repeated that transmission or made sure we acknowledged that transmission; just 'air carrier X; contact departure.' the whole crew discussed this during climb; and thought it was probably a mistake or for another aircraft; especially since he never repeated this and handed us off normally to departure control. The ground handler gave us the 'chocks away' signal before taxi and the aircraft taxied normally. Also; departure control did not relay any irregularities to us. The flight engineer then called in the times to the ground handler and no irregularities were relayed to us. After the crew discussion; with no irregularities noted or relayed and normal flight; everybody thought it was a mistake or for another aircraft. This was a very short flight; only 160 mi. We then started planning for the descent and landing into ZZZ1. We made a normal landing; taxi-in and shutdown. During postflt walkaround; mechanic discovered chocks hanging between right main wheels. Suggestions: 1) if ground handler knew of an irregularity; make sure the aircraft crew receives the message and acknowledges the irregularities. Communicate! 2) at small airport outstations; have mechanic do last min walkaround to doublechk ground handler's removal of the chocks. 3) tower controller should not mumble possible abort to aircraft taking off. Especially for large heavy aircraft departing on a short runway. This is very dangerous! 4) if tower was aware of an irregularity; make sure aircraft crew receives and acknowledges the irregularity! Communicate! 5) ground handler should train to proficiency to make sure this does not happen again!

Title: A B727 DEPARTED AND LANDED WITH THE WHEEL CHOCKS STUCK BTWN THE R MAIN GEAR.
Narrative: DURING A SHORT FIELD TKOF AT ZZZ AT AROUND 100 KTS; THE TWR CTLR MUMBLED SOMETHING ABOUT ABORT AND MISSING CHOCKS. NOBODY OF THE 4 CREW MEMBERS IN THE COCKPIT HEARD HIM CLRLY. NOBODY UNDERSTOOD NOR ACKNOWLEDGED THIS XMISSION! WE CONTINUED THE TKOF ROLL AND CLBED OUT NORMALLY. THE TWR CTLR QUICKLY; SAID 'ACR X; CONTACT DEP' AFTER TKOF. WHICH WE DID. ALL OUR COCKPIT INDICATIONS WERE NORMAL; TKOF WAS NORMAL AND ACFT HANDLING WAS NORMAL. THE CTLR NEVER REPEATED THAT XMISSION OR MADE SURE WE ACKNOWLEDGED THAT XMISSION; JUST 'ACR X; CONTACT DEP.' THE WHOLE CREW DISCUSSED THIS DURING CLB; AND THOUGHT IT WAS PROBABLY A MISTAKE OR FOR ANOTHER ACFT; ESPECIALLY SINCE HE NEVER REPEATED THIS AND HANDED US OFF NORMALLY TO DEP CTL. THE GND HANDLER GAVE US THE 'CHOCKS AWAY' SIGNAL BEFORE TAXI AND THE ACFT TAXIED NORMALLY. ALSO; DEP CTL DID NOT RELAY ANY IRREGULARITIES TO US. THE FE THEN CALLED IN THE TIMES TO THE GND HANDLER AND NO IRREGULARITIES WERE RELAYED TO US. AFTER THE CREW DISCUSSION; WITH NO IRREGULARITIES NOTED OR RELAYED AND NORMAL FLT; EVERYBODY THOUGHT IT WAS A MISTAKE OR FOR ANOTHER ACFT. THIS WAS A VERY SHORT FLT; ONLY 160 MI. WE THEN STARTED PLANNING FOR THE DSCNT AND LNDG INTO ZZZ1. WE MADE A NORMAL LNDG; TAXI-IN AND SHUTDOWN. DURING POSTFLT WALKAROUND; MECH DISCOVERED CHOCKS HANGING BTWN R MAIN WHEELS. SUGGESTIONS: 1) IF GND HANDLER KNEW OF AN IRREGULARITY; MAKE SURE THE ACFT CREW RECEIVES THE MESSAGE AND ACKNOWLEDGES THE IRREGULARITIES. COMMUNICATE! 2) AT SMALL ARPT OUTSTATIONS; HAVE MECH DO LAST MIN WALKAROUND TO DOUBLECHK GND HANDLER'S REMOVAL OF THE CHOCKS. 3) TWR CTLR SHOULD NOT MUMBLE POSSIBLE ABORT TO ACFT TAKING OFF. ESPECIALLY FOR LARGE HVY ACFT DEPARTING ON A SHORT RWY. THIS IS VERY DANGEROUS! 4) IF TWR WAS AWARE OF AN IRREGULARITY; MAKE SURE ACFT CREW RECEIVES AND ACKNOWLEDGES THE IRREGULARITY! COMMUNICATE! 5) GND HANDLER SHOULD TRAIN TO PROFICIENCY TO MAKE SURE THIS DOES NOT HAPPEN AGAIN!
