Actually, proper training directs when on fire...you land immediately (at the nearest suitable airport) regardless of your current weight. The max landing weight for the 757-200 series is 198,000# and the max take-off weight is either 240,000 or 250,000#s depending on the mods done to the jet. That being said, the jet is certified to make an "over weight" landing at the certified max take-off weight with no problems. All that is required is that maintenance come out and make an "Overweight landing inspection" which takes very little time.

Remember the Swiss Air MD-11 that caught on fire after take off from JFK? Had the pilots landed immediately when they realized they had problems (They could have, but the Captain decided to circle to burn off fuel) they would have been fine, but instead all were killed when the fire got out of control. Since then...when on fire...land immediately...period.
